The Hedland Flow Meter is a variable area (rotameter) instrument. A precision machined, sharp-edged Orifice is located within the piston assembly and 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.
Features:
- Install in any position
- 360° rotatable guard/scale
- No electronics needed to obtain a reading
- No flow straighteners or special piping required
- Relatively insensitive to shock and vibration
- Magnetic coupling eliminates the need for mechanical linkages that wear, loosen and leak over the functional life of competitive meters
- Temperature up to 116 °C
- Pressure up to 241 bar max
- Accuracy ±7% full scale
- Repeatability +/- 1%
- Custom scale options to meet exact application requirements

Reverse Flow By-Pass
Flow in reverse direction cases lower cone shuttle to shift moving below the sharp-edged piston orifice.
This shift allows the fluid to flow freely in the reverse direction.
