8.4 Removing the sensor
WARNING!
Removing sensors under pressure can be dangerous!
Be aware that the sensor can be shot out of the ball
valve if you do not carefully follow the steps
described below!
For your information: The sensor is exposed to a force of 18 kg at the
8-bar(g) system pressure; a force of 32 kg at 16-bar(g) system
pressure!! Hold the sensor very tight when releasing the clamp sleeve.
Follow the steps below to remove the sensor:
1. Hold the flow sensor.
2. Release the connection nut at the connection thread.
3. Pull out the shaft slowly.
4. The measuring section can be closed with the optional closing cap
so that the system can operate normally during maintenance of
the sensor.
Follow the steps below to re-install the sensor after maintenance:
1. Place the O-ring into the recess of the connection nut.
2. Insert the sensor back to the pipe.
3. Tighten the connection nut.
