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
