Application and function
For the operation of a facility with streaming gases (e.g. hall exhaust
air, exhaust gases etc.) the continuous registration of the exhaust
gas velocity respectively the flow as well as the temperature are
often of substantial importance. In case of continuous emission measurements
the mass of pollutants has to be disclosed additionally (mass flow
[kg/h]).
The flow measuring device FMD 99 is a measuring device for the continuous
registration of gas velocity and temperature of gas flows in pipelines.
Moreover it is possible to display respectively provide the flow in
operational or norm state. The use of the dynamic pressure and Pt100-measuring
principle guarantees a device simply to install and handle as well
as a timely monitoring of the measuring parameters.
The dynamic pressure probe FMD 99 can be cleaned with the probe cleaning
system PCS 03 in case of high dust contents.
