PFM 5001 Measuring Instrument

Brand: Danfoss

The PFM 5001 has been designed to create hydraulic balance in heating, cooling and domestic hot water systems. It enables measuring of pressure flow and temperatures in a system. 

Using differences in pressure the PFM 5001 is capable of turning these two pressures on both sides of a valve into flow. Flow through individual branches of the system can be measured, creating perfect balance in the whole system.
