Micropilot M FMR231 with FOUNDATION Fieldbus Technical data
Hauser 87
10 Technical data
10.1 Additional technical data
10.1.1 Input
Measured variable The measured variable is the distance between a reference point and a reflective surface (i.e.
medium surface).
The level is calculated based on the tank height entered.
The level can be converted into other units (volume, mass) by means of a linearization.
Operating frequency • FMR231: C-band
Up to 8 Micropilot M transmitters can be installed in the same tank because the transmitter pulses
are statistically coded.
Transmitting power Average energy density in beam direction:
10.1.2 Output
