3.5. Assembly of the measurement ball valve
•
All connections to be made with appropriated sealing material on the threads.
•
The sealing material should not change the area of the inner cross section of the pipe. It must be
warranted that the connections after installation are free of leaks.
•
All fittings must be tested on seal tightness.
•
Make sure during the assembly of the measurement section that the arrows on the pipe section
and the measurement ball valve are pointing in the same direction as the flow.
•
The recess for the alignment pin must be at the side of the outlet.

3.5.1. Assembly without flow meter, but with screw cap instead (blind cap)
In order to use the measurement section without the flow meter, the blind screw cap (in
the scope of supply) must be screwed tight onto the opening of the measurment ball
valve. If not needed the screw cap can be screwed and stored on the handle of the
measurment valve with shut-off function.
3.5.2. Shut off the measurement ball valve
The measurment ball valve assembly allows for the installation and removal of the flow meter within seconds,
with only a very short interruption of the flow.
OPEN
CLOSED
Never remove the flow meter
or the blind screw cap while
the measurement ball valve
is open.
That is extremely danger-
ous!
