Blue And White (F-508E) 12 - 72 GPH; 1-4" MPT
F-508E 12-72 GPH Flow Meter
The Blue & White F-508E flowmeter delivers reliable visual flow monitoring for reverse osmosis systems, deionization loops, and other applications requiring precise measurement in the 12 to 72 gallons per hour range. Machined from a single piece of polished acrylic with corrosion-resistant internals, this meter installs via 1/4" male NPT threads and offers dual-scale readouts for both gallons per hour and liters per hour.
Engineered for Accuracy and Durability
One-Piece Acrylic Body
Machined and polished from a single acrylic block for clarity and leak-free operation with no seams or joints to fail
Corrosion Resistant Internals
Internal components engineered to resist wear and chemical degradation for long service life in water treatment applications
Dual Scale Display
Read flow rates in both gallons per hour (GPH) and liters per hour (LPH) without conversion calculations
1/4" Male NPT Threads
Standard 1/4" male national pipe thread connections for direct installation in most RO and filtration systems
12-72 GPH Range
Optimized for residential RO permeate monitoring and low-flow commercial applications requiring precise measurement
Panel Mount Design
Adapters included for clean panel-mount installation where visibility and monitoring are critical
Where the F-508E Fits
The Blue & White F-508E is compatible with residential reverse osmosis systems, laboratory DI water loops, aquarium filtration, hydroponics nutrient delivery, and any application requiring visual flow confirmation in the 12 to 72 GPH range. The 1/4" male NPT connection is standard on most RO systems and can be adapted to JG, CPC, or compression fittings as needed. This meter is frequently installed on RO permeate lines, recirculation loops, and product water discharge to confirm system performance and detect flow anomalies.
Blue & White flowmeters have been the benchmark for visual flow measurement in water treatment for decades, trusted by installers who need accuracy without electronics.
