King 7511215B-08 Inline Flowmeter 5 Gpm Fnpt Acrylic

Product Description

The KING 7511215B-08 is a block-style inline flowmeter designed for monitoring flow rates in air and water systems. It accepts a 0.5-inch FNPT port connection and handles flow rates up to 5 GPM with a maximum working pressure of 100 psi. The acrylic housing provides direct visual confirmation of flow without additional instrumentation. This meter installs in a vertical orientation and is sized for light commercial and residential plumbing, HVAC hydronic loops, and similar fluid-handling applications. Licensed plumbers, HVAC technicians, and mechanical contractors are the typical installers.

The 7511215B-08 suits applications where a compact, inline flow measurement point is needed on water or air lines operating below 100 psi. The 0.5-inch FNPT block-style port makes it straightforward to integrate into existing threaded pipe runs. The acrylic body allows at-a-glance flow verification without gauges or electronic sensors, making it useful during system commissioning, balancing, and routine service checks on residential and light commercial systems.

Compatibility

Rated for use with air and water. Designed as an inline flow measurement fitting for threaded pipe systems using 0.5-inch FNPT connections operating within the rated pressure and flow limits.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC mechanical technician in accordance with applicable IPC or IFGC guidelines. Shut off system pressure and depressurize the line completely before threading the flowmeter into the pipe run. The unit requires a vertical mounting orientation for accurate readings. PVC fittings are used at the connection points, so avoid over-torquing threaded joints, which can crack the acrylic body.
