FMM hydraulic installation
WARNING
Non-permitted operating pressure
Danger of bodily injury
►
Note the maximum operating pressure.
NOTICE
The minimum differential pressure is < 15 bar
If the minimum differential pressure is not given, measuring errors will
occur.
►
Always observe the minimum differential pressure of 15 bar
To minimize measurement errors resulting from trapped air in the system, we
recommend that the flow direction through the FMM is from bottom (IN) to top
(OUT).
The FMM comes delivered with four test connectors (Type 1604), one at the
inlet (IN) and one at the outlet (OUT) port, as well as at the two testing points
(TP1 / TP2).
If the hydraulic connection is done via the connector thread G 1/4 according
to ISO 228, the test connectors must be removed.
