LZT-1001G Inline Water Flow Meter – 0.1–1 GPM / 0.5–4 LPM

The Inline Water Flow Meter with 0.1–1 GPM and 0.5–4 LPM measurement scales provides clear, convenient monitoring of low water-flow rates in reverse osmosis, filtration, commercial treatment, and industrial water systems.

Its dual GPM and LPM scales allow users to read flow in either U.S. gallons per minute or liters per minute. The transparent acrylic body provides a clear view of the flow indicator, making it easier to monitor system performance, confirm operating conditions, and identify unexpected changes in water flow.

Designed for inline installation, this compact flow meter is a practical monitoring component for water-treatment dealers, equipment manufacturers, system assemblers, service technicians, and industrial users. Optimal Purity Solutions identifies its flow-meter range as having GPM and LPM scales, acrylic construction, and applications in RO, filtration, and industrial water systems.
