The Hedland High Pressure Flow Meter for Phosphate Ester Fluids is a rugged, low cost variable area flow meter. These industrial class in-line meters are design to be used for phosphate-ester fluid measurement. The meters features high quality metal body construction in brass, stainless steel, or anodized aluminum. You can choose from six port sizes from 1/4" to 1-1/2" with flow ranges from 0.02 to 150 GPM (0.1 to 560 LPM).
These variable area flow meters can be used in applications in which the temperature ranges from -20 to 240°F. Stainless steel flow meters are pressure rated for 6,000 psi/414 bar maximum (5,000 psi/345 bar maximum for 3/4" to 1-1/2" series) with a 3:1 safety factor. Aluminum and brass meters are pressure rated for 3,500 psi/241 bar maximum with a 3:1 safety factor.
All Hedland variable area meters use a sharp-edged annular orifice, formed between the open-centered piston and a contoured metering cone. The piston is held in a "no-flow" position at the base of the contoured cone by a calibrated retention spring. Flow through the meter creates a differential pressure across the piston orifice, moving the piston against the spring. The greater the volume, the further the piston moves. Externally, the flow indicator is magnetically-coupled to the moving piston. The indicator is visually "read" against a graduated flow scale.
