Mounting the ball valve (see previous figure)
• Thread the valve end on the but weld end or nipple (use sealing tape or flaxen hair and joint
paste).
The sensor is mounted in the valve using an adapter. The adapter serves two purposes:
1. A thread for the sensor nut to keep the sensor in place.
2. A stop for the lockring to prevent the sensor from coming loose when the sensor nut is loos-
ened.

INFORMATION!
Don not pull the valve end to the bottom. The valve handle plane shall have the same direction as
the pipe. If the valve is turned the wrong way, the measuring gap will not be in line with the flow,
resulting in faulty measurement.
