The Dwyer HFL-4-25 is a one FNPT in-line flow monitor suitable for liquids and compatible gases. This device measures flow through a floating orifice disk and variable area flow measurement. Flowing media causes a linear movement of the orifice disk, which in turn operates a magnet. The external magnet follower indicates the flow rate on the scale.
The device is suited for diverse applications such as setting pressure relief valves and monitoring lubricating liquids. Its design accommodates high viscosities and varies plumbing needs.
