This new line of test kits measures flows in hydraulic and pneumatic systems. "We used to have a barrel-shaped scale that the user read as it moved with the cylinder," says Rich Little, the chief mechanical engineer at Hedland Flow Meters. "You could get different readings depending on how you looked at it," he says. The new flow meters have scales that are easier to read because they are fixed and have larger viewing areas. "We also improved the accuracy of the meters to±2% by tightening up our spring specifications and improving the tolerances in our cylinder pistons," says Little.
The hydraulic test kits measure pressure up to 6,000 psi at flows up to 150 gpm. Pneumatic kits measure pressures up to 600 psi at flows up to 1,000 scfm. All kits install in any position and do not require special piping or flow straighteners. Port sizes from¼to 1½inches are available in aluminum, stainless steel, and brass. In addition to verifying flow rates in trucking applications, the test kits also check pump and compressor performance, measure pressure drops, balance multi-line systems, and locate line restrictions in plastic injection molders, steel mills, and machine tools. The kits can be used as permanent monitoring devices and troubleshooting tools and are compatible with petroleum fluids, phosphate esters, water-based fluids, and compressed gases.
