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.
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.
BENEFITS
No electronics needed to obtain a reading
Can be installed in any position / orientation without affecting accuracy
The most readable product in its class
Does not require special plumbing or accessories to stabilize turbulent flow
Magnetic coupling eliminates the need for mechanical linkages that wear, loosen and leak over the functional life of competitive meters
Custom scale options to meet exact application requirements
