3.10.2 Method 2
Measuring the wall thickness on pipes DN 50 to 4000 (2 to 160").
1. Coat the contact surface of the sensor with an even layer of coupling fluid
approx. 1 mm (0.04") thick.
2. Hold the sensor by hand on the pipe for measurement. Be sure that the horizontal line on the
sensor contact surface is parallel to the axis of the pipe.

3. The sensor can now be connected to the 93T transmitter via the connecting cables.
!
Note!
The polarity of the connections to the 93T transmitter is not important for wall thickness
measurement.
If flow sensors are to be installed after the wall thickness measurement is made, be sure to clean the
pipe surface once again.
