Blue And White (F-451004LHN) 4.0 - 40 GPM Flow Meter; 1" FPT; IL
F-451004LHN Core Specs
Construction & Features
| Model Number | F-451004LHN |
| Manufacturer | Blue & White Industries |
| Body Material | Injection molded polysulfone, chemical resistant |
| Adapter System | Quick Loc half-union adapters for fast installation |
| Thread Type | 1 inch Female NPT (National Pipe Thread) |
| Installation Configuration | Inline (IL) mounting |
| Scale Options | Dual scale and single scale available across F-451 series |
Where This Flow Meter Works
The F-451004LHN is compatible with reverse osmosis systems, whole-house filtration setups, commercial water treatment equipment, and light industrial applications requiring accurate flow measurement between 4.0 and 40 GPM. The 1" female NPT threads connect directly to standard pipe fittings, while the Quick Loc adapters allow for tool-free installation and removal. The chemical-resistant polysulfone construction withstands exposure to chlorine, cleaning agents, and common water treatment chemicals without degradation. Ideal for monitoring flow rates in booster pump systems, post-filtration lines, and process water applications where precise GPM readings are necessary for system optimization and compliance.
