Tightening
The tightening torque of the fastening screws of the flanges should not exceed 32 Nm for
maximum working pressures of 16 bar.
This tightening torque is applicable for wafer sensors (FLOMID-0FX), and with flanges
(FLOMID-2FX) for a pressure value of 16 bar.
The maximum value of the torque depends on the sensor nominal pressure (PN).
The tightening of the flange bolts should be done uniformly, following the sequence indicated
in the drawings according to the number of flange bolts.

MAINTENANCE
It is recommended to clean the electrodes in installations where incrustations or appreciable
sedimentations can occur.
