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 water and other fluid meters are designed to monitor fluid flow rates of water and solvents. These meters closely resemble their water-based fluid counterpart, with the exception of different internal wetted components for fluid compatibility. The standard meters provide an economical solution for operators needing a quick, visual indication of flow, without the use of additional electronics. A variety of end fittings and different material types create product flexibility and material compatibility. Expansion options are available to allow integration into remote systems via electronic output.
