INSTALLATION & USE
Setup Instructions
- Shut off water supply and relieve system pressure before installation.
- Thread the 3/8" FPT connections into your inline plumbing, ensuring proper orientation with flow direction arrow facing downstream.
- Hand-tighten, then use a wrench to secure connections without over-torquing the polysulfone body.
- Restore water pressure gradually and check for leaks at both connection points.
- Observe the dual-scale display to verify flow rate readings during normal operation.
COMPATIBILITY
System Integration
The F-45375L-6 works with residential reverse osmosis systems, whole-house filtration setups, and point-of-use applications requiring flow verification in the 0.1 to 1 GPM range. The 3/8" FPT threads integrate with standard plumbing components, while the chemical-resistant polysulfone housing withstands exposure to chlorine, acids, and other water treatment chemicals. Quick Loc adapters allow for fast installation and removal during maintenance without cutting pipes.
🔧 Pro Tip: Install the flow meter after your filters but before any faucets or dispensers to monitor actual product water output. A sudden drop in flow rate often indicates filter saturation or membrane fouling before you notice changes in water quality.
