LZT-4008G-S Square-Body Inline Flow Meter – 8–80 GPM / 30–300 LPM, 1.5″ FNPT

The Square-Body Inline Water Flow Meter provides clear, dependable monitoring of high water flow rates in commercial reverse osmosis, industrial filtration, water treatment, and process water systems. Its dual measurement scale displays flow rates from 8–80 GPM and 30–300 LPM.

The square-body configuration provides a compact, structured profile for integration into compatible piping and equipment assemblies. Its transparent housing offers clear visibility of the flow indicator, helping operators verify flow rates, monitor system performance, and recognize unexpected operating changes.

Designed for direct inline installation, the meter features 1.5-inch FNPT connections for use with compatible male NPT fittings, piping, and water-treatment components. Its high-capacity measurement range makes it suitable for commercial and industrial systems that require substantial water-flow monitoring.
