8702 Mass Flow Meter

Mass flow meters are used in process technology for the direct measurement of the mass flow of gases. In case of volumetric flow meters, it is necessary to measure the tem perature and the pressure either the density, because gases change their density or rather their volume depending on the pressure. 

The measurement of the mass flow, on the other hand, is independent of the pressure and the temperature. The digital mass flow meter Type 8702 uses a sensor on silicon chip basis located directly in the bypass channel. Due to the fact that the sensor is directly in the bypass channel a very fast response time of the MFM is reached. 

The actual flow is given as an Analog output signal or could be read out over fieldbus communication. Type 8702 can optionally be calibrated for two different gases, the user is able to switch between these two gases. 

The materials of the parts that come into contact with the medium are selected according to customer specification so that the unit can be operated with the complete range of standard process gases. The MassFlowCommunicator software can be used for parameterisation and diagnosis.
