3.13 Installing sensor DDU19
3.13.1 Version 1
1. Premount the strapping band:
– Nominal diameters DN
≤
200 (8")
→
ä
32
– Nominal diameters DN
>
200 (8")
→
ä
33
The two mounting bolts must be positioned opposite each other on either side of the pipe.
2. Fit the sensor holders over the individual mounting bolts and tighten securely with the
retaining nut.
3. Coat the contact surfaces of the sensors with an even layer of coupling fluid approx. 1 mm
(0.04") thick, going from the groove through the center to the opposite edge.
4. Insert the sensor into the sensor holder.
5. Fit the sensor cover on the sensor holder and turn until:
– The sensor cover engages with a click
– The arrows (
Å
/
Æ
"close") are pointing towards one another.
6. Screw the connecting cable into the connections of the sensor.
7. After determining the pipe wall thickness, replace the wall thickness sensor DDU19 with the
appropriate flow sensor.
!
Note!
Clean the coupling point carefully before the flow sensor coated with new coupling fluid is inserted.
3.13.2 Version 2
This is only suitable if the transmitter is within range of the measuring point.
1. Coat the contact surfaces of the sensors with an even layer of coupling fluid approx. 1 mm
(0.04") thick, going from the groove through the center to the opposite edge.
2. Hold the sensor vertically by hand on the pipe for measurement. Operate the local operation
with your other hand.
