King 7510212A-04 Inline Flowmeter 12 Gph 1/4 Inch Fnpt

Product Description

The KING 7510212A-04 is a block-style inline flowmeter designed for monitoring flow rates in air and water systems. It reads up to 12 gallons per hour (GPH) and is rated for a maximum working pressure of 100 psi. The acrylic housing provides direct visual flow indication without additional instrumentation. The 1/4-inch FNPT port accepts standard tube fittings with PVC fitting material. This unit mounts vertically inline and is suited for low-flow applications in plumbing, HVAC auxiliary lines, chemical feed systems, and light industrial service. Installation is handled by licensed plumbers, HVAC technicians, or qualified mechanical contractors.

The 7510212A-04 is built for use with air and water media, making it applicable in residential and light commercial settings where visual flow confirmation is needed. Typical installs include water treatment lines, cooling system bypass circuits, and instrumentation panels where a compact block-style meter fits a tight plumbing layout. The 1/4-inch connection keeps the form factor small, and the inline mount integrates directly into existing tubing runs without branch fittings or tees.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician familiar with low-pressure instrumentation. Shut off and depressurize the line completely before installing or removing the meter. This unit requires a vertical mounting orientation for accurate flow indication — do not install horizontally. Follow applicable IPC or local plumbing code requirements for instrument connections in potable or process water systems.
