Hedland - Basic Phosphate Ester Fluid Meters
Hedland phosphate ester fluid meters provide a measurement solution for fire-resistant fluids, aviation hydraulic fluid and industrial lubricants. These fluids have high ignition temperatures and low vapor pressures. Use in hydraulic applications is considered when fire-risk is concerning. Examples of phosphate esters include Fyrquel, Skydrol and Pydraul. 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.
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.
