The large clear 2-1/2" (63 mm) diameter dial ensures that quick checks can be
made to determine pump performance and setting of flow control valves. They
can be used on mobile and industrial hydraulic circuits. Also lubrication and coolant systems using oil.

These direct acting flow indicators can be installed in hazardous areas or on
applications where no power is available. The flow indicator design ensures
good reliability and minimises the effects of contamination.

The flow indicator consists of a sharp edged orifice and tapered metering

The piston movement is directly proportional to flow rate and the sharp edge
orifice minimises the effects of viscosity. The piston is magnetically coupled to the rotary pointer assembly which registers on a clear 2-1/2" (63 mm) scale displayed in Lpm and US GPM.

The FI750 flow indicators should not be installed in circuits where the flow is reversed.
