ProSense FG1 Series mechanical variable area flowmeters provide visual indication of flow rate for water or petroleum-based fluids. These meters provide ±5% full-scale accuracy and a repeatability of ±1%, important for cyclical applications requiring consistent readings. Two adjustable flow limit pointers are available to provide preset indication of high, low or normal flow rates. The flowmeters are constructed of high-impact polysulfone plastic (body, piston and cone) with brass fittings (½ and ¾ NPT models). They are available with ½-in, ¾-in or 1-in NPT process connections and have easy-to-read flow scales in both gallons per minute and liters per minute.
