The Hedland Flow Meter is a variable area instrument (rotameter). A precision machined orifice with sharp edges is located in the piston assembly and forms an annular orifice with the preformed metering cone. The piston assembly carries a cylindrical PPS/ceramic magnet magnet magnetically coupled to an external current indicator that moves accurately, in direct response to piston movement. A calibrated spring counteracts flow in a forward direction.
This spring reduces viscosity sensitivity and allows the flowmeter to be used in any position, including inverted.
Features:
- Install in any position 360°rotatable protective cap/shell
- No electronics required to obtain a measurement
- No power straighteners or special piping required
- Relatively insensitive to shock and vibration
- Magnetic coupling eliminates the need for mechanical connections that wear, loosen and
leaks over the functional life of competitive meters - Temperature up to 116 °C
- Pressure up to max. 241 bar
- Accuracy ±7% full scale Repeatability +/- 1%
- Custom scaling options to meet exact application requirements
