King 7511212B-08 Inline Flowmeter 5 Gpm 1/2 Inch Fnpt

Product Description

The KING 7511212B-08 is a block-style inline flowmeter designed to measure flow rates in piped air and water systems. Rated for up to 5 GPM and a maximum working pressure of 100 psi, it features an acrylic housing that allows direct visual reading of flow without additional instrumentation. The 1/2-inch FNPT port connects inline with standard piping and must be mounted in a vertical orientation for accurate measurement. With a stated accuracy of plus or minus 5 percent, this meter is suited for monitoring flow in HVAC hydronic circuits, plumbing distribution lines, and light industrial fluid systems. Installation is handled by licensed plumbers and HVAC mechanics.

The 7511212B-08 is rated for use with both air and water, making it applicable across a range of trade installations including hydronic heating and cooling loops, domestic water supply monitoring, and compressed-air line verification. The block-style inline body allows direct in-line pipe installation without tee fittings or bypass assemblies. Its 1/2-inch connection size fits standard residential and light commercial piping configurations where flow verification at specific points is required.
