Optimass Application Story 

Application: Beer Brewing at Grolsch in Holland 

Observe the ice on the pipe above at right! 

OPTIMASS is capable of high 

measurement accuracy of 0.1 % for 

fluids and 0.5% for gasses. Our 

mass flow meters can measure 

density and volume flow as well as 

calculating Brix or Plato with the 

concentration option. 

Grolsch’s tests actually showed 

better than 0.1% accuracy when 

dosing 8 kg batches of hops 

When Grolsch built their new state of the art 

brewery at Enschede, they equipped it with 

KROHNE flowmeters, including OPTIMASS 

meters for the more demanding applications 

where there is high viscosity or no 

conductivity. 

In the brewery applications this includes 

dosing liquid sugar and hops and for 

measuring carbon dioxide levels in the cold 

recovery system.

In the brewing process, the hops are roasted in the pan. There are many different ways of doing this. 

So, too, with Hop extract processing. 

The Optimass T10 measures exact dosing of the Hop extract into a heating chamber at 45°C in 

order to keep the amount used to the minimum required.This means the optimum cost control with 

Optimass. 

To ensure a clear operation and supervision, a galvanically separated output with PROFIBUS © PA is 

deployed.

Optimass 

Why use Optimass? 


Due to the very high viscosity and the subsequent need to reduce the pressure drop, it is necessary 

to choose a meter whose operating point lies in the lower range of the flow rate. 

In this case Optimass shows a marked improvement over the competition. 

Zero Stability 

Various doses were checked against a certified scale. The following diagram shows how impressive 

the performance of the new Optimass was. The low flow cutoff was switched off during the tests.

Coriolis Mass Flow 

Application Story – loading of milk in France 

Cheese Producers sometime have to sell excess milk or buy in from other suppliers 

according to their production demands and quotas. They have various options 

available to measure this. 

Application : 

To accurately record the 

quantity of milk loaded 

into the tanker trucks 

from the storage areas of 

the factory. As the milk is 

pushed through the pipes 

by water, density 

measurement is used to 

determine the cut-off 

point so only milk goes 

into the tankers. 

Why did the customer choose KROHNE: 

The KROHNE sales team in France were able to use 

their experience to help the customer to choose Coriolis 

mass flowmeters instead of the weighbridge option, and 

to demonstrate to his customers that this was a reliable 

billing solution, without having to resort to custody 

transfer transactions. 

Model chosen: 

The OPTIMASS 7000 has the technology. With its 

single straight tube, it is totally cleanable inline and 

approved for hygienic applications. The density 

measurement is used to limit the range of density 

between 1025 Kg/m3 and 1040 Kg/m3, allowing 

differentiation between the passage of the milk and 

the water. 

STRAIGHT TALK 

Benefits to the customer: 

Simple daily operation; reduced investment 

cost with the meter installed online in the 

loading pipes, avoiding the need for civil 

engineering works to build a weighbridge.

Left: On the production line, each 

Optimass meter is simply attached to the 

framework by means of clamps fastened 

around the meter body, something that 

would have been impossible with most 

previous designs of Coriolis mass 

flowmeters. Such an installation would 

have had a detrimental affect on the 

performance of the meter. 

This is now possible with the 7000 Series 

due to KROHNE’s patented 

‘Adaptive Sensor Technology’ which 

intelligently ‘tunes’ each meter, 

independent of external forces and fluid 

density, to produce an inherently balanced 

instrument that remains stable in the most 

demanding processes.

Application 


COUNTRY: UK 


Vegetable oils with a variable loading 

temperature and a viscosity of 

between 8cp and 100cp, are pumped 

from storage tanks at an average 

mass flowrate of 60 tonnes per hour 

using centrifugal pumps. They are 

routed through two separate pipework 

systems, and pass through the 

flowmeters before reaching the loading 

points. The OPTIMASS meters send 

a pulse output to a batch controller to 

measure the mass of oil being 

pumped; when the totalised mass flow 

reaches a predetermined level the 

batch counter stops the pumps. 

Why KROHNE? The refinery has built up a close relationship with KROHNE 

over the past decade after the flow and level company solved installation 

problems experienced with flowmeters. 

Problem: Installation restrictions and achieving batch process accuracy with 

Coriolis meters 

Solution: The innovative design of the 7000 Series, incorporating KROHNE’s 

‘Adaptive Sensor Technology’ ensures total flexibility of installation plus 

superb accuracy and repeatability.

This customer, Tovarna Sladkorja Ormoz, is a sugar producer in Slovenia. 

They use lime milk as a flocculent and require the concentration of lime milk to be 

constant. In order to achieve this they purchased an Optimass T 50 with the 

Baumé concentration option. 

Due to the abrasive nature of lime milk, transition pieces were installed. As the 

Optimass T 50 meter is measuring at the upper velocity limit (6 m/s) for abrasive 

applications, after three months' operation the KROHNE agents in Slovenia made a 

resistance check and removed the instrument to see if any damage on the transition 

piece or instrument had occurred. More than 47,000 tons of lime milk had passed 

through the instrument but there was no trace of wear, either on the transition piece 

or on the instrument. 

The customer was very satisfied with the measurement.

Application Story – Bio-Ethanol Production in US & Canada 

Fuel Ethanol (200 Proof) is a renewable, clean 

burning & high octane fuel that is better for the 

environment than gasoline. It is also biodegradable 

and far less toxic than fossil fuels 

and can be used on its own (E100) or blended 

with gasoline (E10, E85 etc). 

Ethanol can be produced from starch/sugar rich 

feed stocks such as grains/cereals (corn, wheat, 

rice etc) , potatoes, cassava, beet/sugar cane and 

today even from cellulosic biomass sources viz. 

wood chips, switch grass, corn stover's, municipal 

waste, recycled paper etc. 

Of all these feed sources the Dry Grind/Milling 

process used for corn (or wheat) feed is the most 

popular in US & Canada. Typical OPTIMASS 

applications on a Dry Grind/Milling process 

(shown on right) include density measurement for 

slurry tanks , liquefaction mash, syrup draw , 

rectified & final proof measurements. 

Slurry #1 Density ( Slurry Preparation) 

Combined Flow/Density measurement using 

our OPTIMASS 7000 series (S50 straight 

tube) on the evaporator syrup draw 

application (shown below) provides a high 

investment return by improving the overall 

dryer process efficiency downstream of the 

evaporators. 

Evaporator Syrup Draw 

STRAIGHT TALK 

Krohne Inc has over 60+ installation ( and 50 more on order) of 

OPTIMASS 7000 series (S25/S50 tubes) on the corn 

slurry/mash & syrup applications . Additionally on each of these 

plants our 7000 series (S15 tubes) are installed on liquid 

ammonia feed lines that feed nutrients into the slurry tanks and 

fermentors. 

Liquefaction Mash 

(feed preparation for fermentors) 

Corn Slurry and syrup drawn from evaporators 

can be extremely nasty & viscous and will clog 

almost any bent tube designs - it is here that 

the single straight tube Optimass offers 

significant benefits. 

Also lower pressure drop is a desirable feature 

as energy optimization is of utmost importance 

on these high energy intensive processes. It 

are for these reasons that Krohne is able to 

demonstrate value over our competitors.

Varnish Production at BASF Coatings AG 

BASF Coatings division develops, produces and markets a range of top quality innovative 

vehicle, car repair and industrial varnishes and coating materials for buildings and offers 

the corresponding coating processes. The Münster site is one of the biggest varnish plants 

in the world with a total area of 400,000 square meters. 

In order to operate the mobile paddle 

mixers used in the colour grinding process 

without supervision over 36-48 hours BASF 

used a flowmeter to trigger a leakage 

alarm. This meter needed to fulfill high 

specifications in terms of accuracy. The 

properties of the media made things even 

more difficult. The raw materials for 

varnishes are high-viscosity media which 

are processed at a low flow rate. They 

have viscosities of 7000mPas and over, 

and are also shear thinning - their behavior 

changes with the flow rate. The DN 40 

flowmeters also have to cope with high 

pigment contents. BASF Coatings did not 

want to risk any further pressure loss 

otherwise they would have to increase the 

performance of the pump. BASF Coatings 

thus opted for the OPTIMASS, a mass 

flowmeter which is virtually made for this 

application thanks to its straight-tube 

design. 

The grinding system is designed for a flow rate of 

approx. 5000kg/h. Communication with the PLC takes 

place via the OPTIMASS's 4…20mA signal output. 

Every 90 seconds the PLC saves a flow 

measurement and compares it with the subsequent 

values. If there is a difference of 360kg/h, the system 

is automatically shut down. At present, further tests 

are underway to halve the leakage value. 

Why 

KROHNE? 

• Less pressure loss 

• Less abrasion 

• Suitable even for large flow volumes 

• Wide measuring range 

• No risk of blockage

The liquefied gas is distilled into several fractions which are used as active 

ingredients in pharmaceutical products. It was essential that F2 Chemicals 

found a way to measure the flow of the liquid reliably to ensure the 

consistent, high quality of its products. 

The measurement technology F2 Chemicals previously used to measure 

the flow of liquefied perfluorobutane and acetone did not provide the 

reliability which was critical for F2’s process. 

Perfluorobutane and acetone are contained in 100 litre industrial cylinders and are 

charged into the distillation column and refluxed through the OPTIMASS Coriolis 

mass flowmeter at flow rates of between 40 and 200 kg/hour and at pressures of 

between 2 and 7 bar. The temperature of the liquefied gas varies between -5°C 

and +15°C. A 20 mA signal is taken from the OPTIMASS and fed into a DCS. 

The reading is manually monitored and the distillation 

process adjusted according to temperature. 

Measurement reliability improved significantly since the 

KROHNE OPTIMASS 8000 Coriolis mass flowmeter was installed. 

STRAIGHT TALK 

F2 Chemicals installed 

KROHNE’s OPTIMASS 8000 

Coriolis mass flowmeter 

because of its ability to 

measure liquefied gas 

reliably and accurately at low 

temperatures. Its twin “u” 

shaped measuring tubes 

provide excellent signal-tonoise 

ratio and measurement 

turndown. This was 

important considering the low 

pressures of the gas being 

measured. 


Application Story: Liquid Sulphur measurement in Russia 

Ammofos AG at Cherepovets is one of 

the leading Russian manufactures of 

phosphate fertilisers, and part of the 

chemical conglomerate JSC Fosagro AG 

The focus of the company is the 

production of sulphuric acid. Raw 

materials used in production are sulphur 

and pyrite. 

OPTIMASS 7050 T25 mass flowmeters 

are used to measure the flow of molten 

sulphur with a temperature up to 145°C. 

Ammofos plant in Cherepovets 

Problem: The temperature has to be kept above 130°C to prevent the 

sulphur from hardening and crystallising, and other measurement systems 

encountered problems. 

Solution: The Optimass meter with its efficient heating jacket prevents the 

product solidifying. The great advantage of the single straight tube meter is 

its low pressure drop. The other advantage is that, if the product does 

solidify the straight tube is easy to clean out and restart the process.

Optimass Mass Flowmeters in 

Loading Systems 

Mass flowmeters of the Optimass family from KROHNE through their 

unique performance specifications are extensively used in various 

industrial applications for operating measurements and batching. 

However, this is far from being the only 

application area of these mass 

flowmeters. Growing prices on many kinds 

of products lead many plants and 

companies to look for effective methods of 

online monitoring of fluid operating flows, 

as well as measuring the quantities of 

product delivered to the buyer in business 

dealings.

Application Story Akzo Nobel UK 

World leading producer of paints and coatings, Akzo Nobel 

Decorative Coatings, has installed four KROHNE 

OPTIMASS Coriolis Mass flowmeters at its manufacturing 

plant in Darwen, Lancashire to help accurately control 

product consistency and minimise production costs. 

Accurately measuring the amount of chemicals added to Akzo Nobel’s Crown 

range of solvent-based paint products is essential to minimising costs and 

maintaining consistent product quality. The chemicals are contained in stainless 

steel storage vessels located 70 meters away from the production facility and are 

pumped at low pressure through the OPTIMASS flowmeters into mixing vessels 

where the paint is manufactured in batches. 

Signals from the instruments are fed into the production control system which 

controls the flow of the chemicals from the storage vessels to ensure that the 

correct amount is added. 

Previously Akzo Nobel measured the amount of chemical added to batches of 

paint using a load cell-based weighing system. However this did not provide 

sufficient measurement accuracy for the range of batch sizes. 

The OPTIMASS 7000 Series, with its single straight measuring tube, features a 

patented AST design which offers outstanding accuracy and stability when used 

on low flow rate applications. 

By installing our OPTIMASS meters, Akzo Nobel has automated the process and 

significantly improved measurement accuracy. 

The installed meters are 

2 x OPTIMASS 7000 T25s measuring Calcium and Lithium, 

1 x 7000 T15 measuring Cobalt 

1 x 3000 S01 measuring silane monomer.

Application Story - PTFE production in England 

Asahi Glass Fluoropolymers UK Ltd installed four 

KROHNE OPTIMASS 7000 T10 flowmeters to 

measure heavy gas flow at its polytetrafluoroethylene 

(PTFE) manufacturing plant in Lancashire. Each 

OPTIMASS replaced 2 previous measuring devices for 

pressure and temperature. 

Tetrafluoroethylene (TFE) is a dense, almost liquid, 

heavy gas used in the production of PTFE. 

The TFE gas is produced in a separate area of the factory and pumped into the PTFE 

manufacturing plant through a common pipeline 24 hours per day. The common gas 

feed is then split into four lines to produce different grades of PTFE, each of which is 

fitted with an OPTIMASS flowmeter.

Sand Separation 


INDUSTRY: MINING 

COUNTRY: SWEDEN 


Råda Sand AB is a producer and supplier of fine sand to various industries 

including concrete, filtration manufacturer etc. To be able to get the fine sand 

out of the water, they have to add the right amount of flocculent chemicals to 

settle the sand. The mass concentration controls the whole process in a ratio 

with the volume flow. We supplied the customer with an Optimass MFM7050 

T 40. 

Application: Flocculent 

Dosing 

Why KROHNE? 

Problem 

The customer required 

accurate dosing of the 

flocculent (inorganic 

coagulant) due to the high 

price of the flocculent and to 

improve efficiency. 

Solution 

The only equipment suitable 

for the customer was the 

Optimass due to its single 

straight tube, which is less 

susceptible to abrasion. 

The fluid is very abrasive due to its sand content (

The Adaptive Sensor Technology of 

Optimass removes the problem of external 

influences affecting measurement by using its 

own internal mass as a self compensating 

mechanism therefore responding quickly to 

changes in density. 


Salt Mining in Austria 

Shortly before its 25th Anniversary, Saline Austria in Ebensee 

modernised its installation in order to optimise production 

processes and minimise environmental impact. 

The brine tanks accumulate a slurry of chalk and 

gypsum at the bottom which has to be drawn off 

periodically. This led to a lot of the brine also 

being lost. However with the use of Optimass 

meters to measure the density, the valves can be 

closed as soon as pure brine is measured. The 

slurry density is around 1.3 kg/l and drops to 1.15 

with pure brine. 

Additionally a KROHNE Optimass is helping to improve the environmental impact as 

the waste water slurry from the process is no longer discharged into the Traunsee Lake 

but pumped back from Ebensee via a 20 km pipeline where it is forced into the salt 

caves of Bad Ischl which in turn displaces new brine. This is then returned by a 

separate pipeline. Here also, the KROHNE meter is being used for density control. 

Application: Salt production 

Why KROHNE? 

Problem: 

Loss of brine when slurry drawn off 

Solution: 

Prompt shut-off with Optimass density 

measurement

Paper Coating Plant produced by OEM customer, BVG 

for Paper Mill in Germany 

Application: Discontinuous Paper Coating 

Our customer BVG in Greifenberg is an important Original Equipment Manufacturer 

(OEM) for the paper industry operating world wide. The installation of this extremely 

compact discontinuous coating kitchen was made by BVG’s Dr. Bauer at a paper mill 

in Germany. 

BVG have also developed innovative continuous coating plants for other customers 

with on line coating and on line satinage using our Coriolis meters. 

Problem 

The problem for the end user lay in the recipe for the coating colour. There were 

always bonding problems between the background and the coating. This could have 

been caused because the required level of dosing accuracy was not achieved with the 

previously used positive displacement meters. Getting accurate and responsive 

measurements of the highly viscous and dense products batched such as clay, latex, 

carbonate and dispersants was difficult.

Application Stories 

Density Measurement of Carbonate Slurry in the Paper Industry 

The measurement of the density of Carbonate slurry has 

evolved considerably in the last few years in the paper 

industry and in particular at this customer in Finland. 

Initially the density was measured using Radiometric 

density meters and, combined with an Electromagnetic 

flowmeter, the mass flow was calculated. Here Berthold 

density meters and KROHNE IFM5110F Magnetic 

Flowmeters were used. 

Later on this measurement method was discontinued due 

to the ‘percieved’ dangers of Radiometric measurement 

and Single Straight Tube Coriolis meters were used to 

replace this technology. The process involves and 

evaporation process where the slurry is continuously 

circulated till the correct density is achieved in the 

evaporator. The Carbonate slurry is then pumped to a 

storage tank. A KROHNE 300 G+ was used for this 

process. In the initial production and mixing of the slurry 

and 800G+ was used. Further enhancement of the 

process was made using the Multi I/O option in the mass 

meters. This provided the plant engineers with more 

data with respect to the process, apart from density, eg 

temperature, mass flow etc. 

Later orders of mass flowmeters from KROHNE had the 

Profibus PA option which gave the plant engineers more 

flexibility in the control and monitoring of the plant. 

New Evaporator 

When it was decided to install a new evaporator the 

natural progression was to use the new Optimass 

meters from KROHNE. 

This project was started in October 2002 and fully 

commissioned by May 2003. Here an Optimass 

MFM7051 T40 with Profibus PA was used. 

KROHNE Magnetic flowmeter Model IFM 5090 

WITH Profibus PA was used for water addition to 

the process.

measurement of the mass. If there is an overload, the truck must come back to an offloading 

station, losing valuable operating time. If the tanker is not totally filled, then transportation costs 

increase. 

The previous installation was less than ideal, and 7 larger meters were replaced with Optimass 

T 40 and T 50 meters without any pipeline modifications. This was a requirement, as Shell was 

not able to stop the loading stations in order to do the work. 

The measurement results were immediately excellent without any special adjustment or field 

calibration of the meter. For a 26 ton fill, the measurement accuracy improved to ±0.2% with 

Optimass from the previous ±0.8 to 2.5%. 


Application: Loading Station 

Why KROHNE? KROHNE France provided the support and convinced the 

customer that they could save money with the increased 

accuracy of the installation of Optimass. 

Problem: Unsatisfactory performance of existing meters. 

Solution: Improved accuracy meant more savings.

Application Story – Wax Production in UK 

UK wax manufacturer Kerax Limited has installed an 

OPTIMASS 7300 mass flowmeter to improve the 

accuracy of production processes at its plant in 

Chorley, Lancashire. 

Application: 

Kerax produces a variety of different waxes to be used in making castings and as 

ingredients in products such as adhesives. Each formulation requires the 

blending of two or three types of wax plus a number of additives. The mechanical 

meter previously positioned on the input to the blending vessel was not able to 

provide the accuracy needed for Kerax’s increasingly stringent process control. 

Problem: 

The wax flowing through the 

meter can vary in density from 

0.8 to 1.0 kg/litre and in 

viscosity from 5.5 cP to 1,200 

cP. It can be flowing at rates 

varying from 1.8 to 15 tonnes / 

hour with pressures from 1.4 bar 

to more than 4.1 bar at 

temperatures ranging from 20 to 

120°C. 

Solution: OPTIMASS 7300-T 50 

The installed OPTIMASS 7300 

Coriolis mass flowmeter is capable 

of handling the wide variation in 

process conditions whilst still 

delivering accuracy of +/- 0.1 per 

cent. 

STRAIGHT TALK 

To maintain a consistent product 

temperature, the OPTIMASS meter is 

fitted with a heating jacket that can be fed 

with hot water or steam. 


Application Story – Siemens Gasification Test Rig 

STRAIGHT TALK 

The Siemens gasification centre 

in Freiberg, Germany, is one of 

the most comprehensive 

gasification test facilities in the 

world. Its gasification reactor is 

rated at five MWth and can be 

adjusted to different feedstock 

conditions. The facility also 

includes a range of feedstock 

preparation systems and related 

gas cleaning process units. 

A test rig for large-scale, high-pressure feeding tests and further equipment for coal 

and slag analysis (e.g. fluidization and viscosity) complement the facilities. With this 

equipment, a broad range of test conditions can be simulated. 

For the examination of fouling in heat exchangers, 

a test rig was designed to gain experience when 

preheating process water up to 220°C. Thermo oil 

is used as a heating medium in the heat exchanger. 

Both the monitoring of temperature and a reliable 

monitoring of the volume flow are decisive factors 

for the evaluation. 

An OPTIMASS 9000 from KROHNE was installed 

to control the thermo oil volume flow. The mass 

flowmeter records the volume flow of the thermo oil 

at 230 °C and 10 barg. The maximal permissible 

temperature of the thermo oil is 300°C.

Top gas mud density measurement in Nova hut a.s. 

ISPAT Nova Hut a.s. is one of the largest metallurgic plants in the Czech Republic. 

It is an integrated steelmaking concern with a metallurgical production and large 

engineering shops. The metallurgical production is of a mass character, the main 

products being welded and hot-rolled seamless steel pipes, long products and wire 

rod, hot rolled sheets and strips. The engineering production (e.g. steel mining 

supports) is geared for batch production. Their coking plant is the largest coke 

producer in the Czech Republic. 

ISPAT Nova Hut has been using several hundreds of KROHNE magnetic inductive 

flowmeters and flow controllers (mainly on water measurements) and additionally 

ultrasonic flowmeters (on demineralised water and tar), level radar (blast furnace 

stock level, hydrochloric acid level measurement) and mass flowmeters (fuel oil, top 

gas and steel sludge measurement). All instruments have been subjected to 

demanding operating conditions. 

In the blast furnace, during the pig iron production process, a lot of top gas is 

generated. The gas (with temperature 200 – 500°C) contains from 30 to 100 g/m3 of 

dust. The gas is cleaned with sprinkling water, which then flows into settling basins. 

Here the mud settles and then it is pumped first to thickeners and after thickening to a 

separator. For the process control it is necessary to know the density of the mud 

pumped from basins to thickeners and from thickeners to the separator. 

The customer had been using nucleonic density meters for 10 years. These meters 

require special approvals and checks and a lot of maintenance. Moreover they could 

not be in operation without product flow. For this reason the customer decided to test 

2 KROHNE mass flowmeters Corimass MFM 4085 G+ - 1500 G. After 6 months´ 

testing, 8 pieces of Optimass T50 mass flowmeters were ordered.

Application Story – Fuel Consumption in Norway 

4 Optimass 1300 C S25 meters were purchased for fuel monitoring on ferries in 

Norway with very good results. The first installation is now saving about 1000 litre 

diesel per day, which is about 120.000 Euro p.a. The second pair have now been 

commissioned on another ferry and we expect more orders to be forthcoming. 

The logging system is delivered by Bentzen Elektro. It uses 2 of our very precise 

OPTIMASS 1300C flow meters that measure the difference between input and 

output. One meter is on the input side of the fuel line and one on the return pipe. 

The difference measures the fuel consumption. 

The basis of the system is a 6.5’’ TFT 

colour screen displaying the consumption 

based on different criteria, like time or 

distance travelled. The screen has a 

touch function and is easy to operate. 

There is an alarm function to show when 

the consumption is too high. The log 

function is in the screen and is saved in 

an USB-stick, which can be down loaded 

to a PC to keep a history of consumed 

fuel. 

The system is very flexible and can be 

extended where required to log the 

consumption with regard to number of 

revolutions, pitch or speed,

Czech Republic Custody Transfer 

A T25 Optimass Meter was installed for Propane/Butane emptying of rail tankers 

with a capacity of approximately 42000 kg at BP in the Czech Republic. Accuracies 

of 0.2 to 0.3% were repeatedly achieved which included the uncertainty of the 

weighbridge used for the railcars. Resolutions of these weighbridges are typically 

in the tens of kilograms! This meter is installed as a Custody Transfer meter 

according to Czech Republic guidelines and directives. 

All weather emptying from railway tanks using Optimass 

Another Optimass T25 for Custody 

Transfer was subsequently 

installed at BP in Dysina near the 

city of Pilsen filling tank-trucks 

with propane/butane. The 

measurement error is approx. 30 

kg per 10000 kg of the gas, but it 

also comprises the error of the 

recomputation as the tank-trucks 

are filled according to mass but the 

distribution to end users is 

performed according to volume and 

the recomputation to mass is done 

acc. to special tables. 


Application:CT transfer of bulk 

Butane / Propane products 

Flow Rate: 12000 kg/h 

Pressure: 6-8 bar 

Temp: Ambient (-30 to +35°C) 


Application: CT transfer of bulk Butane / 

Propane products 

Flow Rate: Nominal flow rate of a 25 T 

is 34,500 kg/h, emptying at 14,000 kg/h 

(pressure drop 0,3 bar, velocity 15,4 m/s) 

Pressure: 7 to 12 bar 

Density: 560 kg/m3 

Temperature: Ambient (-30 to +35°C)

Propane-butane measurement for the BP CZ company, used for filling from railway 

tanks under the environment conditions (outside), the instrument is „custody 

transfer“ acc. to the CZ directives, during the first filling the tank contained 41100 kg 

with the pressure of 5 bar, our Optimass measured by 120 kg minus, the customer 

was satisfied. 




Applications – Oil & Gas 




Applications – Oil & Gas 




The customer needs to load the exact 

quantity of SAP oil into the tanker to avoid 

any overloading. The trucks are then 

weighed on a weighbridge to get a custody 

transfer measurement. If there is an 

overload, the truck must come back 

to an offloading station, losing valuable 

operating time. If the tanker is not totally 

filled, then transportation costs increase.
