As the leading manufacturer of hydraulic flow measurement solutions, the Hedland product line features over 15,000 inline, variable-area flow meters to measure hydraulic oils, compressed air and many other liquids and gases. This large range of meters ensures that there is a meter suitable for most industrial applications that require hydraulic and pneumatic measurement.
Operating Principle
Hedland flow meters are variable area instruments, as the hydraulic oil or compressed air enters the meter, it is directed around a contoured metering cone located within the piston assembly. The pressure differential created by the flow around the cone causes the piston to move against the spring. The piston assembly carries a cylindrical PPS/Ceramic Magnet that is magnetically coupled to an easy-to-read linear flow scale that moves precisely, in direct response to movement of the piston for a quick visual indication to confirm systems are operating correctly.
