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.
Hedland air/compressed gas meters are designed for use in pneumatic systems. Additionally, with a variety of end fittings and different material types, these meters can be used in a wide range of industrial gas flow processes as well as monitoring compressor efficiencies and pneumatic tool usage. Standard meters provide an economical solution for operators needing a quick, visual indication of flow, without the use of additional electronics. Expansion options are available to allow integration into remote systems via electronic output.
