Water and Oil Indicators/Monitors – LARGE

The large series units are designed to be robust, highly versatile and extremely reliable in the harshest of environments. They continuously monitor flow with a local indication, through a mechanical pointer, switch, transmitter or digital rate totaliser and can be manufactured in a variety of materials to suit a wide range of liquid, air and gas applications.

This unique modular design allows for easy field installation and service. No straight run of pipe is required before or after the monitor, minimizing pressure drop and the installation footprint. Vane-style flow meters have a spring-opposed vane that moves in relation to the flow rate. The fluid forces the vane to move through a contoured opening creating a variable orifice; the greater the flow the larger the orifice becomes for flow to pass. The vane style monitor is spring loaded and allows the vane to return on decreasing flows.
