A Pipes: internal diameter
Ducts: internal dimension
B Wall thickness
C Dimension from pipe/duct to the compression fitting
!
Note!
For detailed remarks on calculation refer to Technical Information TI069D.
• Calculated insertion depth (SI units)= 0.3 · A + B + C + 2 mm
• Calculated insertion depth (US units) = 0.3 · A + B + C + 0.079 inch
Note down the calculated value.

5. Insert the sensor into the socket (1) and tighten the lower nut of compression fitting (2) first
by hand and then tighten it 1¼ revolutions using a wrench (42 mm).

Caution!
– NPT thread: use a thread sealing tape or paste
– G 1 A thread: the sealing ring supplied must be installed
6. Tighten the upper nut of compression fitting (3) such that the sensor can still be adjusted.
7. Read off the calculated insertion depth from the scale and adjust the sensor so that the value
aligns with the upper end of the compression fitting (4).
