Flo-tech”s PFM Tester Series now features an internal burst disk to support simultaneous measurement of flow, pressure and temperature on hydraulic machines. The PFM line is being implemented on all units to include the internal burst disk component. The design will help ensure that in the event of an over-pressurization, flow remains uninterrupted. Maintenance costs and environmental harm is reduced because the internal design prevents fluids from traveling outside of the tester. The PFM Tester utilizes a turbine rotor and a magnetic pick-up to measure flowrates by measuring the pulse from the rotor and transferring the signal to a provided LCD display or PC screen. The device provides high accuracy of 1 percent of full scale and a repeatability of 0.2 percent. Temperature is also measured with an internal sensor, as well as an analog or digital pressure sensor. For ease of use and safety, all testers have loading valves with fingertip control and pressure surge protection.
