This equipment is designed to be installed directly in the
distribution pipe line. The meter has a 1/2" BsP connection
at both inlet and outlet. it also includes an inlet flange and
an outlet flange with seating for an O-ring seal.
avoid installing the unit between rigid connections to
prevent efforts transmission of the pipeline.
it is recommended to install a pressure relief system on the
line to prevent damage from thermal expansion.
To prevent damage from dirt or solid particles carried by
the fluid is recommended the installation of a 200-mesh
strainer at the unit inlet.
it is advised to install the solenoid valve associated to the
u-meter at the unit inlet. Do not install the solenoid valve
at the unit outlet to avoid the unit being pressurized when
