Induction flow meter FMG600 series
Electrode axis
Sensor mounted in a vertical position
In the cases where the sensor is mounted in a vertical position, the flow direction shall always be upwards.
Risk of liquid aeration
Permanent flooding of sensor
To ensure correct meter function at all times, the measured liquid shall completely fill up the sensor and no
air bubbles shall be permitted to accumulate or develop in the sensor tube. Therefore the sensor shall never
be placed in the upper pocket of the piping or in a vertical piping section where the flow direction is
downwards.
In piping systems where complete flooding of the piping cannot always be guaranteed, consider placing the
sensor in a bottom pocket where full flooding is sure.
If the sensor is located near a free discharge point, such point shall be by at least 2 DN higher than the top
part of the sensor.
