HEDLAND AIR/GAS FLOW METER OPERATING PRINCIPLE

The Hedland Air/Gas flow meter is a variable area instrument. A precision machined, sharp-edged Orifice located within the Piston Assembly, 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.


The Hedland Variable Area Flow Meter product line includes over 10,000 in-line flow meters, designed to monitor oil, phosphate ester, water and water-based emulsions, air and other compressed gases. Hedland offers flow meters constructed of high-performance materials including:

Anodized Aluminum, Brass, and Stainless Steel. The Hedland meters are easy to install, operate in any position (no flow straighteners or special piping needed) and are accurate to 2% of full scale.
