To avoid damaging the meter by cavitation, downstream pressure must be superior to the head loss generated (0,6 bars at maximum flowrate).

Also, any parts reducing the upstream diameter of the meter should be avoided.


The meter should be installed horizontally within a tolerance of ±10° with the register facing up to be compliant to the specifications given.

During its service, the meter must be permamently fixed and protected against freezing.

To install correctly the meter, place a two-way valve upstream and clean the pipeline before installing the meter.


Gradually fill the meter with water when installed in a pipe or vent any remaining air when using a test bench.


The installation of a filter does not interfere with the normal operation of the meter even if it is not necessary to have one. 


If a backflow occured, the presence of a check valve is mandatory.
