LZT-2520M Panel Mount Flow Meter – 2–20 GPM / 10–70 LPM, 1-Inch MNPT

The Panel-Mount Water Flow Meter with 2–20 GPM and 10–70 LPM measurement scales provides clear and convenient flow monitoring for commercial reverse osmosis, water filtration, industrial treatment, and process-water systems.

Its panel-mount configuration enables secure installation on an equipment panel, control enclosure, or system faceplate. This design keeps the flow scale clearly visible while supporting a clean and organized equipment layout.

The dual measurement scale displays flow in both U.S. gallons per minute and liters per minute. Its clear acrylic housing and stainless steel float provide easy visual monitoring, helping operators verify flow rates, evaluate system performance, and recognize unexpected changes in operating conditions.

The 1-inch MNPT connection supports threaded installation with compatible female NPT fittings and water-treatment components. Its expanded flow range makes this meter suitable for commercial and industrial applications requiring higher flow capacity.
