Flo-tech”s PFM Tester Series is designed to measure flow, pressure, temperature, and horsepower on mobile hydraulic equipment. Effective immediately, all PFM Testers will include an internal burst disc component. The new design ensures that in the event of an over-pressurization, the fluid is safely allowed to bypass the load valve and remain within the hydraulic system. Maintenance costs are thereby reduced, and potential harm to the environment from spills is eliminated with the internal design. The internal burst disc is field-replaceable should an over pressurization occur. The device utilizes a turbine rotor and a magnetic pickup to measure flowrates by measuring the frequency pulse output from the rotor. Volumetric flowrate is displayed on an LCD or sent via digital output to a PC. The PFM Series provides an accuracy of 1 percent (full scale) and repeatability of 0.2 percent. Temperature is measured via an internal sensor, and pressure is measured via an analog gauge or high-sensitivity digital sensor. For ease of use and safety, all testers have loading valves with fingertip control and pressure surge protection.
