Installing the measuring sensors Prosonic Flow P

2 or 4 traverses version
1. Fix a tensioning band for small or large nominal diameters as described on
Page 21. Install the second tensioning band (threaded stud on the opposite side).
The second tensioning band must still be moveable.
2. Determine the spacing between the distance holes (sensor distance).
!
Note!
To determine the spacing between the distance holes (sensor distance) use:
– the "Sensor Installation" Quick Setup menu if the measuring device has a local
operation. Use the Quick Setup as described on Page 76. The sensor distance is
shown in the POSITION SENSOR function (6886), (i.e. a letter on the mounting rail
for sensor 1 and a number for sensor 2). The transmitter has to be installed and
connected to the power supply to carry out the "Sensor Installation" Quick Setup.
– the procedure described on Page 84 ff. if the measuring device has no local
operation.
3. Arrange the tensioning bands to the sensor distance shown in the POSITION SEN-
SOR function. Place the mounting rail on the threaded studs and then fasten the
second tensioning band. Remove the mounting rail.
4. Fix the sensor holder to the pipe using the threaded studs. Tighten the locking nuts
using a spanner (AF 13).
5. Fasten the mounting rail brackets to the sensor holders using a Philips screwdriver.
Place the mounting rail on the threaded studs and then fasten the appropriate
srews.
6. Coat the contact surface of the sensors with an even (approx. 1 mm thick) layer of
coupling fluid (from the centre to the groove, see Page 98).
Then carefully insert the sensor into the sensor holder. Press the sensor cover onto
the sensor holder until you hear a click. Make sure that the arrows (
the sensor housing and sensor holder are pointing to each other. Then insert the
sensor cable plug into the opening provided and manually tighten the plug to the
stop.
