Mass Flow Meter for Gases (MFM)

The mass flow meter (MFM) Type 8700 is especially suited for measuring the mass flow of aggressive gases, which need a sensor which is not in direct contact with the gas. The thermal capillary sensor reaches fast response times.

Type 8700 can optionally be calibrated for two different gases; the user can switch between these two gases. As electrical interfaces both, analog standard signals and fieldbuses are available.
