The latest PFM Tester Series from 2565 Flo-tech now features an internal safety pressure relief disc.

The proven PFM products have a long track record for measuring flow, pressure, temperature and power on mobile hydraulic equipment. However this improved version now features and internal burst disc designed to ensure that in the event of over-pressurisation, fluid is safely allowed to bypass the load valve and remain within the hydraulic system. The feature means that no fluids will escape from the tester, reducing maintenance costs and preventing the need for environmental clean-up from spills. The internal burst disc is also field-replaceable, should an over- pressurisation occur. The PFM Tester uses a turbine rotor and a magnetic pick-up to monitor the frequency pulse output from the rotor and measure flow. Volumetric flow rate is displayed on an LCD or sent through a digital output to a PC. The PFM Series units are said to provide reliable readings with an accuracy of 1% of full scale and a repeatability of 0.2%. Temperature is measured with an internal sensor, and pressure is measured by analogue gauge or high-sensitivity digital sensor. For ease of use and safety, all testers have loading valves with fingertip control and pressure surge protection.
