LZT-1005M-V Panel-Mount Flow Meter with Valve – 0.5–5 GPM / 2–18 LPM, 1/2″ FNPT

The Panel-Mount Water Flow Meter with Valve provides convenient measurement and adjustment of water-flow rates in reverse osmosis, water filtration, commercial treatment, and industrial water systems. Its dual scale displays flow from 0.5–5 GPM and 2–18 LPM.

The integrated adjustment valve allows operators to regulate flow directly at the meter. Its panel-mount configuration enables secure installation on an equipment panel, control enclosure, or system faceplate, keeping the flow scale and adjustment valve visible and accessible.

The clear acrylic housing provides easy visual monitoring of the stainless steel float, helping operators confirm flow rates, evaluate system performance, and identify unexpected operating changes. The meter’s 1/2-inch FNPT connections support threaded installation with compatible male NPT fittings and water-treatment components.
