2 . 1 .3 Mounting instructions for monitoring head CST

Caution!
The two sensors (M) should be screwed into the pipe far enough to ensure that they are aligned
side by side directly across the direction of flow. The sensors are correctly positioned when the
wrench flats (S) are aligned parallel to the pipe.
The sensors must be positioned fully in the flow stream.
The arrow on the housing must point in direction of flow.
Horizontal pipelines:
Monitoring head should be
mounted on the underside.

2 . 1 .3 . 1 Depth of immersion

For inside pipe diameters up to 56 mm shaft end should be in line with the inner pipe wall. Preferably
the shaft surface of the monitoring head should project approx. 1-2 mm towards the pipe centre.
For inside pipe diameters more than 56 mm the shoulder of the two sensors (7 mm from the tip)
should be positioned at 1/8 of inside pipe diameter Ø i (see fig. 10).
For sealing use hemp, teflon tape or thread sealing glue.
