7.2.1 Maintenance of the flowmeter sensor
We recommend checking the cleanliness and state of wear of the flowmeter sensor
rotor periodically. Proceed as follows to carry out this operation:
1. Unscrew the sensor ring nut completely (Figure 9) and extract the sensor from
the main body (there will be some resistance from the O-ring);
2. Make sure that dirt is not found on the rotor or between the rotor and ceramic
axis;
3. Make sure there is no mechanical clearance on the rotor shaft

4. Reinsert the sensor, making sure that the fixing notches match

(Figure 10);

Excessive clearance means a range which is higher than 1 mm.

Before screwing the ring nut, it is necessary to remove the resistance of the O-ring
and check that the sensor does not turn inside its seat.
