3.3.11 Installing the wall thickness measuring sensors DDU 19
(accessories)
Variant 1
1. Fix a tensioning band for small or large nominal diameters as described on
Page 17.
2. Coat the contact surface of the sensor with an even (approx. 1 mm thick) layer of
coupling fluid (starting from the groove, through the centre and to the opposite
side). Then carefully insert the sensor into the sensor holders. Press the sensor
cover onto the sensor holder until you hear a click. Make sure that the arrows

( / "close") on 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.
3. After determining the pipe wall thickness, replace the wall thickness measuring
sensor DD 19 with the appropriate flowmeter measuring sensor.
Note!
Do not forget to clean the coupling point carefully before you insert the flowrate
measuring sensor coated with the coupling fluid.
Variant 2
This is only suitable for as long as the transmitter Prosonic Flow 93 is within arm's length
of the measuring point. Coat the sensor surface from the centre to the groove with an
even (approx. 1 mm thick) layer of coupling fluid (see Page 117). Then hold the sensor
vertically on the pipe for measurement. Operate the local operation with your other
hand.
