Inline Flow Indicator With Temperature Sensor, FI750 Series, Up to 48 GPM


Flow Indicators are designed for continuous monitoring or intermittent use commissioning and servicing hydraulic systems up to 6000 psi (420 bar).  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 minimizes the effects of contamination.

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

The piston movement is directly proportional to flow rate and the sharp edge orifice minimizes 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.
