The active part of the flowmeter sensor W “Insertion” can be replaced without interrupting the
process.

sensor cover in place.

4. Remove the large retainer ring (5). This keeps the sensor neck (6) in place.
5. The sensor neck can now be pulled out. Note that you must reckon with a certain amount of
resistance.
6. Pull the sensor element (7) out of the sensor holder (8) and replace it with a new one.
