Reversible Inline Flow Indicator With Temperature Sensor, RFI Series, Up to 54 GPM


The RFI reversible flow indicator is designed for continuous monitoring or intermittent use commissioning and servicing hydraulic systems up to 6000 PSI (420 bar).

The large 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 anywhere on mobile and industrial hydraulic circuits to test pumps, motors, valves and cylinders.

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.
