Blue And White (F-451003LHN) 3.0 - 30 GPM Flow Meter; 1" FPT; IL
F-451003LHN 3.0 - 30 GPM Flow Meter
Inline flow monitoring for municipal and commercial water treatment systems. 1" FPT Quick Loc connections, injection-molded Polysulfone construction rated for 3.0 to 30 gallons per minute.
Built for chemical resistance and real-time flow verification
Accurate Flow Range
Dual-scale readout optimized for 3.0 to 30 GPM applications. Monitor reverse osmosis permeate, well water delivery, or filtration system output with reliable mechanical metering.
Quick Loc Adapters
Half-union Polysulfone Quick Loc fittings on both ends allow fast installation and removal without cutting pipe. 1" female NPT threads fit standard industrial plumbing.
Chemical Resistant
Injection-molded Polysulfone housing resists chlorine, acids, and alkaline solutions common in water treatment. No corrosion, no degradation from sanitizers or pH adjusters.
Inline Configuration
The F-451003LHN is configured for inline mounting directly in the pipe run. Clear visual confirmation of flow rates without digital electronics or external power.
System integration and installation
The Blue & White F-451003LHN flow meter installs in any 1" NPT plumbing system. Common applications include reverse osmosis skid monitoring, municipal well output measurement, filtration system diagnostics, and commercial water treatment verification. Works with fresh water, treated water, and most water treatment chemicals. Not recommended for petroleum products or solvents outside municipal water treatment use.
Visual Confirmation
No batteries, no calibration. Read flow rates at a glance during commissioning and service.
Service Access
Quick Loc design allows meter removal for inspection or replacement without system downtime.
Industrial Grade
Polysulfone construction handles commercial water treatment environments without brittleness or cracking.
