H2FLOW Controls fv-4-l Flowvis Flow Meter 4 Inches Lpm

Product Description

The H2FLOW CONTROLS fv-4-l is a 4-inch precision flow meter designed for accurate, reliable flow measurement in gray water and potable water systems. Built as a complete FlowVis Tee in SCH80 construction, it delivers readings on an LPM scale with a pressure rating of 50 psi. The patented internal design eliminates the need for straight-pipe runs upstream or downstream, which is a common installation constraint with traditional flow meters. Licensed plumbers and pool service technicians install this type of device in commercial and residential water systems where consistent flow measurement is required.

The fv-4-l is suited for 4-inch plumbing installations handling gray water or potable water. Its flexible orientation support makes it a practical choice for tight mechanical rooms, pump pads, and equipment pads where available straight-pipe runs are limited. The SCH80 tee body provides added wall thickness and durability compared to standard Schedule 40 fittings, making it appropriate for demanding service environments.

Key Features

• LPM scale for direct flow rate readings in liters per minute
• 50 psi pressure rating suitable for typical residential and light commercial water systems
• SCH80 tee body construction for added durability and wall thickness
• Patented design eliminates straight-pipe run requirements adjacent to other fittings
• Installs horizontally, vertically, or inverted for maximum placement flexibility
• Compatible with gray water and potable water applications

Compatibility

Designed as an OEM-style precision flow meter for 4-inch gray water and potable water plumbing systems.

Installation Notes

Installation is typically performed by a licensed plumber or qualified pool and spa technician. Shut off water supply and relieve system pressure before beginning work. The SCH80 tee body is solvent-welded into the existing piping run following applicable IPC guidelines for the pipe material in use. Confirm the scale orientation is visible and readable after securing the fitting in its final position.
