Multitec BioControl
Determines the composition and
volume of biogas, sewer gas and
landfill gas
All plant operators producing electricity from biogas, sewer gas
or landfill gas aim to optimise processes and thus ensure greater
efficiency – in other words, obtain as much methane as possible.
At the same time, however, harmful components in the gas need
to be kept to a minimum.
Only constant monitoring of the gas composition in a plant can
indicate changes before it is too late and thereby prevent
prolonged outages. For example, if there is a warning of too
much sulphur at the measurement location before the motor, the
operator can act immediately to stop the motor from being
destroyed.
If the power generation is subsidised, the plant operator must
regularly document the gas composition and volume.
®
The Multitec BioControl can reliably and sustainably handle
all these tasks, though dirt, deposits, moisture, corrosion and
fluctuating gas compositions still pose a major challenge. The
intelligent compensation of pressure, temperature, moisture and
gas composition means that the components can be analysed
®
with precision. The Multitec BioControl can also determine
the temperature and flow rate.

Multitec BioControl
One system for stationary and mobile measurements
® ®
The Multitec BioControl is a combined measuring device consisting of the Multitec BioControl fixed installation and a mobile
®
gas measuring device, namely the Multitec 540.
®
Depending on the version of Multitec BioControl , the gas composition and volume can be automatically measured and monitored
®
at up to eight measurement locations. The Multitec 540 measures the values at the individual measurement locations sequentially.
®
The values are transferred to the Multitec BioControl via an interface.
®
The mobile gas measuring device must be regularly maintained to guarantee accurate measuring results. The Multitec BioControl
allows easy maintenance for the versions with four and eight measurement locations as standard, with automatic calibration and
adjustment with test gas.
®
The Multitec BioControl fixed installation is non-wearing and low maintenance. All that is required is a regular check for dirt on the
flow rate and temperature sensor and cleaning if necessary. This can be done in a few minutes whilst measuring. The mobile
® Multitec 540 gas measuring device can be easily sent in for servicing. A spare device prevents disruption to operation.
Mobile measurements
Individual measuring locations can also be set
up for mobile, i.e. manual measurement if
®
preferred. The Multitec 540 is simply taken
®
out of the Multitec BioControl docking
station for the measurement. When it is
replaced in the docking station following a
mobile measurement, the stored logs are
®
transferred to the Multitec BioControl and
displayed.
Mobile measurements allow you to integrate
even remote outdoor measuring points reliably
and cost-effectively in the system. ATEXcertified
flow rate and temperature transmitters,
which can be permanently installed outdoors,
are available as optional accessories.

Multitec 540 as a mobile gas measuring device
®
The Multitec 540 is a gas measuring device for monitoring
gas mixtures that are formed in biological processes. It can
measure the concentration of up to five gases in the gas mixture
simultaneously. The device is fitted with infrared sensors for
measuring methane and carbon dioxide as standard. It can also
be fitted with electrochemical sensors.
The use of infrared measuring technology for methane and
carbon dioxide eliminates erroneous results caused by
®
interaction with other gases. The Multitec 540 is, therefore,
ideal for use in biogas plants as well as waste disposal sites and
sewage plants. A large screen allows all parameters to be
displayed simultaneously and quickly read off at a glance.
Features
· Intuitive, menu-driven user interface with jog dial and
function keys
· Large transflective, i.e. semi-transparent display, excellent
readability, even in direct sunlight
· Selective infrared sensors for hydrocarbons and
carbon dioxide
· Highly durable electrochemical sensors for oxygen and
toxic gases
· Power supplied by four replaceable AA-size rechargeable
batteries or disposable batteries
· Minimum seven hour battery life in operation,
rapid charging in four hours
· Explosion protection: II2G Ex d e ib IIB T4 Gb /
II2G Ex d e Ib IIC T4 Gb with TG8 carrying bag
· EC type-examination certificate: TÜV 07 ATEX 553353 X
