3.6.2. Installation of the sensing probe
Make sure that the measurment ball valve is shut off.
•
Remove transport protection cap of the head of the sensing probe.
• Mount the sensing probe in the measurment valve with shut-off function in such a way that the
alignment pin fits in the recess on the measurement ball valve.
• Screw the retainer nut by hand so far that a certain resistance is noticeable.
• Check the correct installation position of the flow meter. The alignment pin must fit in the recess on
the measurment ball valve.
• Tighten the red coloured retainer nut by hand. Tightening by hand should be sufficient. However, if
the seal is not leak tight carefully tighten the nut with an appropriate tool a bit further
• The mechanical installation of the flow meter is therewith completed.
Flow Direction
3.6. Installation of the flow meter sensing probe
3.6.1. Flow direction
The flow direction is indicated with an arrow on the tip of the probe. Due to the alignment pin is the installation
of the sensing probe in the measurment ball valve only possible in the direction of the flow. After a removal,
the sensing probe will be re-installed in the measurement section in exactly the same position as done at the
factory. Hence, the highest reproducibility is guaranteed.
