Dwyer HFPC and HFPS Series Plastic In-Line Flow Meters are indicators for flow rate. Dwyer’s flow meters are ideal for the measurement of a range of compatible gases, oil, or water-based liquids. Applications include deionized water flow, pickling, compressed gases, harsh environments, coolant lines, and industrial applications. The Series HFPC & HFPS In-Line Flow Meters are a series of clear body, in-line flow meters. This Series consists of the HFPC polycarbonate body flow meter and the HFPS polysulfone body flow meter. These flowmeters have dual scales measuring both in GPM and LPM.

Flow includes Flow Transmitters, Flow Sensors, Flowmeters, Sight Flow Indicators, and Water Meters. Mass Flow meters, Controllers, Flow Indicators, and Controllers are ideal for the measurement of flow rates. Flow Switches come as a paddle, thermal, piezo, and shuttle/piston. Flow meters indicate flow rate. The different sensors include dial, in-line, ultrasonic, orifice plate, totalizing meters, variable area, venturi, or switch output. The different designs of the flow meters have a variety of applications.
