9.6 Installing and removing the Flow W sensors
The active part of the flowrate measuring sensor W can be replaced without interrupting the
process.
1. Unscrew the sensor connector (1) from the sensor neck (2) and pull it out.
2. Unscrew the sensor neck (2) from the sensor holder (5). Note that you must reckon with a
certain amount of resistance.
!
Note!
When performing these assembly and disassembly tasks, hold the sensor holder (5) in place with a
wrench (AF 36)! For safety reasons, the sensor holder (5) and the sensor nozzle (6) are screwed
together by a left thread.
1. Pull out the sensor neck.
2. Pull the sensor element (4) out of the sensor holder (5) and replace it with a new one.
3. Check whether the O–ring (3) is intact and replace it with a new one if necessary.
4. Installation is the reverse of the removal procedure.

Warning!
Risk of accidents! During operation, do not unscrew the sensor holder (5) from the sensor nozzle
(6) of the Prosonic Flow C measuring tube as to do so may cause medium to leak!
