3.6. Installation KMT-4 in the pipe line
The patented non-return protection device for reliable installation combines three functions in one unit:
• Non-return protection device
The sensor can only be pushed in one direction during installation. The sensor will not move back at all,
even when it is released.
• Seal
Thanks to an encapsulated O-ring, no compressed air can escape under pressure during assembly.
• Precise positioning
The precise positioning with respect to immersion depth and orientation is easy to perform, guarantee-
ing accurate measurement results.
An example installation is described below using the weld-on nipple in combination with the 1/2“ ball valve.
The same basic principles apply to installation with the tapping sleeve.
•
Pull the measurement sensor back into the non-return protection device as far as it will go.
•
Screw the non-return protection device into the ball valve using suitable sealants for a fully sealed
connection.
•
Screw knurled nut in by approx. one thread turn.

•
Open the ball valve and dip the measurement sensor into the pipe line.
•
Positioning in the pipe line
To ensure that the accuracy level specified on the data sheet is observed, the sensor head must
be positioned in the centre of the pipe. The scale on the sensor pipe for the immersion depth
relates to the centre of the sensor head.
