ProSense FG1 series mechanical variable area flow meters from AutomationDirect 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 flow meters are constructed of high-impact polysulfone plastic (body, piston, cone) with brass fittings (1/2 and 3/4 NPT models). FG1 series flow meters are available with 1/2, 3/4 or 1 in. NPT process connections and have easy-to-read flow scales in both gallons per minute (gpm) and liters per minute (lpm). Measurement ranges are from 0.25 – 2.5 gpm (1 to 10 lpm) to 4 – 28 gpm (20 to 100 lpm).-manifold blocks
