Blue And White (F-45375L-6) 0.1 - 1 GPM Flow Meter; 3/8" FPT; IL
Technical Details
| Model Number | F-45375L-6 |
| Flow Range | 0.1 - 1.0 GPM |
| Connection Size | 3/8" Female Pipe Thread (FPT) |
| Material | Injection Molded Polysulfone |
| Configuration | Inline (IL) Mount |
| Scale Type | Dual Scale Display |
| Adapter Style | Quick Loc (1/2" Union) |
| Chemical Resistance | High (Polysulfone Construction) |
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.
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.
