Page 2: Theory Of Operation
5. Use of engine rated particulate filters is recommended Theory of Operation The Airmar DFM operation is based on the measurement of fuel volume passing through the flow chamber. The fuel pressure passing through the chamber causes the ring slides along the inner wall to rotate, which generates a pulse used to measure volume. -
Page 3: Electrical Connection
The flow meter can be installed up to 30 degrees of incline (fuel output up) Electrical Connection The DFM comes equipped with a M12 Device Net connector to aid in a quick and easy connection. Sensor Connections should be made to the secondary bus of the ASM as dictated by the ASM Installation guide for Digital Sensors. -
