Fuel Flow Transducer | 7-160 GPH, Hall Effect, Straight Pick-up

Product Description

This fuel flow transducer (EDMO# 660534HS) mounts to the engine fuel line and produces electrical signals that represent the fuel flow. The transducer body has hydraulic fittings that connect directly to the engines fuel line, and a small turbine wheel mounted inside with two precision ball bearings driven by the flowing fuel which incorporate a small magnet that is picked-up by a hall-effect sensor. Transducers based on hall effect technology can operate over a broader range of flow rates and in high temperature environments. This transducer also includes an integrated RTD temperature sensor.
