3.3.6 Installing the measuring sensors Prosonic Flow U (clamp-on)
1. In the case of pipes in the DN 15…32 nominal diameter range, use the retaining vee (a)
supplied to reinforce the pipe. This retaining vee is only included in the DN 15….40 installa-
tion set (see Accessories on Page 75). Loop the tensioning bands (b) through the retaining
vee as illustrated below. Pull the tensioning bands freely through the tensioning band locks to
such an extent that the bands can later be guided over the ends of the sensor assembly (please
note that the screw of the tensioning band lock must be opened).

2. Determine the sensor distance.
!
Note!
To determine the 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 64. The sensor distance is shown in the SENSOR
DISTANCE function. 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 67 ff. if the measuring device has no local operation.
The U sensor is designed for 2 traverses only. Please ensure that “NO. TRAVERSE: 2” is
selected for the number of traverses in the SENSOR CONFIGURATION function
(see Page 64).
