MECHANICAL INSTALLATION

The RVL (Wafer) series transmitters are designed with wafer style flow bodies, which mount easily be-
tween standard ANSI style pipe flanges.

Observe the upstream piping requirements listed under “Piping requirements”.

Upstream valves should

Qot Ee used to FoQtrol ÀoZ rate. They should always be kept fully open. Good quality ball valves with
integral unions may be connected directly to the flow meter if the valves are fully open during operation.
This allows easy isolation and removal of the flow meter, should maintenance be required. Cavitation
and flow rate pulsation will adversely affect flow meter performance.
