Installing Prosonic Flow W sensor
3.6.1
Installing Prosonic Flow W (DN 15 to 65 / ½ to 2½")
Mounting the sensor
Prerequisites
• The installation distance (sensor distance) is known ä 14.
• The sensor holder is already mounted ä 15.
Material
The following material is needed for mounting:
• Sensor incl. adapter cable
• Connecting cable for connecting to the transmitter
• Coupling fluid for an acoustic connection between the sensor and pipe
Procedure
1.
Set the distance between the sensors as per the value determined for the sensor distance.
Press the sensor down slightly to move it.

2.
Coat the contact surfaces of the sensors with an even layer of coupling fluid
(approx. 0.5 to 1 mm / 0.02 to 0.04") thick.
3.
Fit the sensor housing on the sensor holder.
Note!
• Avoid to use a thick layer of the coupling fluid (less is more).
• Clean and reapply new coupling fluid when sensor is removed from the pipe.
