FMS-2

Equipment function – face velocity: Measurement of the face velocity using the optional face velocity transducer VS-TRD. The velocity can be set
Equipment function – differential pressure, external measurement: Measurement of the differential pressure at a suitable measurement point using an external differential pressure transducer. 2 pressure values can be monitored
Equipment function – volume flow rate, external measurement: Monitoring of the volume flow rate by measuring the volume flow rate or differential pressure at a suitable measurement point using an external differential pressure transducer or the actual value signal from a volume flow controller. 2 volume flow rate values can be monitored
