To ensure correct and safe use of the meter, please first read and comply with the instructions
and warnings in this manual.
Incorrect installation or use of the meter could cause injury or material damage.
Once the meter has been installed, please make sure that there are no risks of damage to the
meter due to excessive pressure or particles in the fluid. Please check that all connections are
leak proof.
For accurate metering it is essential that there is no air in the fluid supply.

2. Installation
The meter can be installed in any orientation directly in a distribution pipeline/hose or can be
connected to a control valve to be used as a hose end meter. Use sealant on the connection
threads. The inlet / outlet of the meter have 1/2” female threads.
The meter has one preset flow direction (fig. 2).
In the case of a hose end meter installation, in order to ensure a leak free connection between
the pistol and the hose fitting with a 1/2” male thread, we recommend to install the pistol as
follows:
• Clean all eventual dirt and grease from pistol swivel and the hose connector threads.
• Brush the 1/2” male hose connector thread with liquid sealant. Ensure that no sealant gets
into the pistol.
• Screw the pistol and hose connector together. Take care to avoid damaging the pistol swivel.
• The sealant manufacturer’s instructions should be strictly followed.
• The meter installation should only be carried out by qualified staff.
If particles or other solids get into the measuring chamber, then the meter may not measure
correctly and could be damaged, therefore it is recommended to install a 400 micron filter
upstream. The user is responsible for the selection of appropriate components and compliance
with applicable regulations.
