Induction flow meter FMG600 series
In the cases where the liquid is pumped, the flow sensor shall always be placed at the output side of the
pump to prevent underpressure in the piping which might damage the sensor. The required length of the
straight piping section between the pump and sensor is then at least 25 DN.
Pump in the piping Closing valve in the piping
For the same reason, the sensor shall be always placed before the closing valve in the piping.
The sensor can be fitted in the piping in either horizontal or vertical position. However, make sure that the
electrode axis is always horizontal and, if the sensor is mounted in a horizontal position, the flange section
for attachment of the electronic unit box faces upwards.
