3.3.4 Installing the Prosonic Flow W measuring sensors
(Clamp On)
2 or 4 traverses version
1. Fix a tensioning band for small or large nominal diameters as described on
Page 17.
Do not fasten the second tensioning band. You must still be able to move the sec-
ond tensioning band along the pipe.
2. Use the "Sensor installation" Quick Setup to determine the spacing between the
distance holes (sensor distance) as described on Page 60. The sensor distance is
displayed in the "Sensor distance" function, (i.e. a letter between A...K for sensor 1
and a number between 10...76 for sensor 2).
Note!
To run the "Sensor Installation" Quick Setup, the transmitter must be installed and con-
nected to the power supply.
3. Place the mounting rail on the threaded bolts and then fasten the second tensioning
band. Remove the mounting rail.

4. Fix the sensor holder to the pipe using the threaded bolts. Tighten the locking nuts
using a spanner (AF 13).
5. Coat the contact surface of the sensors with an even (approx. 1 mm thick) layer of
the coupling fluid (from the center to the groove, see Page 67).
Then carefully insert the sensors into the sensor holders.
Press the sensor cover over the sensor holder until you hear a click. Make sure that
the arrows affixed to the sensor housing and sensor holder (
ing to each other. The insert the sensor cable plug into the intended opening and
manually tighten the plug to the stop.
