Installing and removing the W sensors

The active part of the flowrate measuring sensor W "Insertion version" can be replaced without
interrupting the process.
1. Pull the sensor connector (1) out of the sensor cover (3).
2. Remove the small retainer ring (2). This is located on the top of the sensor neck and keeps the
sensor cover in place.
3. Remove the sensor cover (3) and spring (4).
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 retainer (8) and replace it with a new one.
7. Installation is the reverse of the removal procedure.
