1.3 Required differential pressureDensity transducers of the DIMF series measure independently of flow rate and also at flow rate zero.Their application is therefore normally problem-free. Care must, however, be taken to ensure that theoperating flow rate in the transducer- updates the sample fast enough- equalizes the temperature in the tranducer- avoids air or gas bubbles ordeposits in the oscillating tube- does not cause cavitation in the oscillating tube- does not cause wear through abrasivesRecommended operating flow rate through the density transducer:DIMF 2.0: approx. 2.0 l/minPressure loss diagramPressure loss∆P [bar](H 2 O; 20°C)101DIMF2.00.10.010.0010.1 1 10 100Flow rate [l/min]DIMF2.00 1.5 6 50 l/min2 l/minPermissible flow ratesRecommended flow0.1 110 1000.01 0.11 10l/minm³/hWe reserve all rights of ownership and exploitation in respect of thesedocuments, including industrial property rights.

2 Intended useThe density transducer type DIMF allows the continuous measurement of the density of liquids and liquidmixtures. The proven oscillating element principle ensures great accuracy in combination withoutstanding long-term stability. The easy-to-get-on-with-construction assures reliable operation, evenunder tough process conditions.3 Measuring principleThe real sensor of the density transducer is an oscillating element in the form of a tube bent into a tuningfork. The liquid to be measured passes continuously through this element. Excited electromagnetically byan excitation coil, it will oscillate at its natural frequency. Changes in the density of the liquid lead tochanges in the natural frequency. This change in frequency, sensed by a pick-up coil, represents themeasurement effect. An additional built-in resistance thermometer measures the process temperature,which can also be used to equalize the temperature influence in the transducer.Each density transducer is calibrated with different liquids of different densities. The transducer constantsfor the calculation of the density from the frequency, the calibration temperature and the correctioncoefficients for temperature influence are given under section 16.4 Example of configuration log.4 Installation examplesIn principle, the density transducer can be installed directly into the product line (for permissible flowrates, see section 1.3). For higher flow rates or measurements at containers, installation in a by-pass isrecommended.4.1 By-pass installation4.1.1 Standard configurationPartShut-off valve ø12Straight tube fittingQty.22We reserve all rights of ownership and exploitation in respect of thesedocuments, including industrial property rights.

9 On-site adjustmentAn on-site adjustment is carried out if an error has been detected due to certain changes in on-siteconditions, after the reasons according to section 13.1 have been checked. By changing the transducerconstant K 0 , a simple adjustment can be performed.Example:Measurement condition Temperature must be relatively stableRho (measured density) = 996.6 Kg/m³Rho (setpoint value) = 996.0 Kg/m³ (e.g. value stated in table)difference (misalignment) = +0.6 Kg/m³current K 0 value = -7360.708 Kg/m³setpoint K 0 valuecorrect K 0 value= K 0 (current) – misalignment= - 7360.708 Kg/m³ - 0.6 Kg/m³= -7361.308 Kg/m³Now this value must be entered into the transmitter type TR.If possible, the constants K 1 and K 2 should not be modified by the user.10 Configuration, operationThe transmitter can be configured (operated) in two different ways:1. HART ® communication2. On-site operation with keys and display10.1 Operation via HART ® communicationThe device can be operated using a PC or laptop and the SensorPort 2 configuration software inconnection with a HART ® interface.A HART ® Communicator is another operating element which can be used (e.g. model HC-275 ofRosemount).

10.1.4 Output signalUpper rangevalueLower rangevalue:Selection ofmeasured variable:Current simulation:Alarm 21.8 mA:Characteristic value for the 20-mA point.Characteristic value for the 4-mA point.The measured variable has been assigned to the HART ® primary variable andthus to the current output. When displaying density, the user can changebetween operating or reference density. When calculating the concentration,the user can select between the two different methods.In order to test the devices connected in series, a fixed outputcurrent of 3.9 to 22 mA can be set. After the test, the current value0 mA must be entered to end simulation.An alarm signal can be transmitted via the current loop.The current then rises to 21.8 mA. This alarm is generated due to amaloperation of the DIMF. The alarm function can be switched off.10.1.5 Special settingsElectronic adjustmentCalibrate current output: The characteristic of the analog current output can be calibrated in its zeropoint at 4 mA and in its slope at 20 mA. It must be observed that the zero pointwill be calibrated before the upper range value.Reset device:With this command, the device can be restored to a defined operating statepresent after the supply voltage was applied.10.2 Operation with the keys (configuration via the control unit)To access the keys, the screw cover of the longer end of the housing must be opened. When the housingcover has been opened, the degree of protection of the housing is not ensured.After the configuration has been completed, the housing cover must be remounted and the screws mustbe fastened fingertight (be careful not to damage the sealing ring).!For the Exd version the housing may only be removed after it has been ensured thatthere is no explosive atmosphere.The covers of the Exd version are secured against opening. In order to open the cover, the locking barmust be swiveled sideways and clamped in this position. After closing the covers, they must beresecured.10.2.1 DisplayThe transmitter type TR has a two-line display with 8 digits for each line.

10.2.5 Programming modeDepending on the operating mode, in programming mode, the device parameters and the mediumconstants can be programmed or modified on site. The constants can only be programmed in the lowerline. For this, the "P" key must be actuated until the first digit blinks in the display field. This digit can thenbe changed with the keys " " or " ". Pressing the ↵ key moves you to the next entry position(corresponding digit blinks). To place a comma, you press the P key for a short moment. After leaving thelast position, the channel is accepted with the current contents. By pressing the P key for approx. 3seconds the current input position can be reset to the previous position.- while programming the K 0 and K X0 values all measured andcalculated values are frozen;the upper display line will not be activated.- if the "programming" function has been initiated but not terminated,it will be terminated automatically after approx. 2 minutes;the old value will be restored.- channel no. "]“ is used for displaying error codes;these can be deleted by pressing the "P" key(see error code table in section 13.2.1).10.2.6 Operating modeBy selecting the operating mode (channel E) you define the calculation method according to which themeasured variable is to be acquired and the output signal is to be represented.By selecting the operating mode you define- the assignment of the primary HART ® variables (current output signal)- the measured value in "channel 0"- the calculation method (see section 11).The analog output signal (4 to 20 mA) can be freely assigned to the desired measuring range (lowerrange value: channel 5, upper range value: channel 6) within the meter range.The minimum measuring range span should not be below a density range of 5 kg/m³.We reserve all rights of ownership and exploitation in respect of thesedocuments, including industrial property rights.

11.4 Determination of the hydrometer degreesFor the determination of hydrometer degrees the computation of the reference density is made byequation 3. The reference temperature is for this firmly given. The equations for the conversion of thehydrometer scales, as well as the respective reference temperature are arranged in the following table:hydrometer degreereference temp.t in °Cliquidsheavier than waterliquidslighter than waterBrix-Fischer15,625(12,3°R)400400400 − − 400ddBaumé (rationell) 15144,30 144,30144,30− − 144, 30ddBaumé (american)15,56(60°F)145140145 − − 130ddBalling 17,5Twaddle15,56(60°F)200200200 − − 200dd200(d− 1)-API (linear)S.G.

For this theconnection is given e.g. between concentration, density and temperature c=f(ρ•t) in tabular form. Thetable may contain maximally 400 mesh points, with maximally 80 lines or 80 columns. The materialvalues must be present as Excel table in the following form:ρttemperaturee.g. concentration tabledensityconcentrationc(max. 400 mesh points*)* e.g. 80 density values at 5 temperaturesThe calculation of the concentration takes place via linear interpolation. The unit results from the giventable codes. The mesh point tables from available material values and the transfer of the mesh pointvalues to the meter take place with SensorPort via program "DIMF table" (see for this operatinginstruction to the program "DIMF table").We reserve all rights of ownership and exploitation in respect of thesedocuments, including industrial property rights.

12 MaintenanceTwo measures are recommended: cleaning and zero point adjustment.CleaningThe density transducer should be cleaned when, for example, liquids tending to sedimentation aremeasured. The easiest method is to increase the flow velocity through the density transducer to themaximum permissible value for some minutes to flush away sediments and solids. If this measure doesnot prove successful, the density transducer should be cleaned with a special detergent if flushingconnections are provided. In this case the corrosion resistance of the wetted parts of the densitytransducer must be observed.Zero point adjustmentAbrasion, sedimentation or corrosion may shift the zero point of the density transducer. The zero pointshift can be established by a comparison measurement and rectified by an on-site adjustment (seesections 9 and 13.1).13 Error detection/troubleshootingPeriodical checks of the density transducer facilitate error detection and may provide information aboutpossible error sources.These checks can normally be limited to a comparison between the measured value and a referencemeasurement, using either lab equipment or a density transducer as a master.For this purpose it is essential that the test equipment is of sufficient reliability and accuracy (e.g. testequipment approved by the Weights and Measurement Authorities) to ensure correct results. During thetest, the conditions must be comparable to the actual operating conditions; if necessary, the temperaturecoefficient of the liquid must be taken into consideration.If the measured value does not match the result of the reference measurement, the following measuresshould be taken:- Check the evaluation electronis (transmitter):electrical connection, power supply, cabling to the transducer.- Ensure that the data of the calibration log or theservice list and the programmed parameters of the evaluation electronics are identical.- Inspect the density transducer for damage(temper colors on the transducer housing caused by high temperature and othermechanical defects such as damaged transmitter housing, damaged gaskets or terminals).- Look for disturbances from process side (e.g. empty product lines or gas bubbles).A seriously damaged density transducer should be dismounted and returned to the service department ofBopp & Reuther Messtechnik (see section 15).Otherwise, additional inspections should be performed. In general, there are three types of error sources:- errors/defects caused by the liquid- errors/defects caused by the transmitter- errors/defects caused by the density transducerWe reserve all rights of ownership and exploitation in respect of thesedocuments, including industrial property rights.
