OIL FLOW METER OPERATING PRINCIPLE

The Hedland oil flow meter is a variable area instrument. A precision machined, sharp-edged Orifice located within the Piston Assembly , forms an annular opening with the contoured Metering Cone . The Piston Assembly carries a cylindrical PPS/Ceramic Magnet that is magnetically coupled to an external Flow Indicator that moves precisely, in direct response to movement of the Piston. A calibrated Spring opposes flow in the forward direction. This spring decreases viscosity sensitivity and allows the flow meter to be used in any position, including inverted.
