King 7510212A-08 Inline Flowmeter 44 Gph 1/4 Inch Fnpt

Product Description

The KING 7510212A-08 is a block-style inline flowmeter designed for monitoring fluid flow in plumbing, HVAC, and light industrial applications. Built with an acrylic housing, it provides a clear visual indication of flow rate up to 44 GPH at a maximum working pressure of 100 psi. The 1/4-inch FNPT port accepts standard tube fittings with PVC fitting material, making it straightforward to integrate into existing water or air lines. Licensed plumbers, HVAC technicians, and mechanical contractors typically specify this meter for diagnostic and commissioning work where real-time flow verification is required.

This flowmeter is suited for residential and light commercial applications involving air or water lines. Its vertical mounting orientation and inline mount type make it appropriate for installations where the meter is plumbed directly into a supply or return line. The block-style body keeps the footprint compact, fitting cleanly into tight mechanical spaces. The 1/4-inch connection size accommodates common small-bore tubing used in hydronic systems, cooling equipment, and water treatment setups.

Key Features

• Maximum flow rate of 44 GPH for air and water service
• 100 psi maximum working pressure
• 1/4-inch FNPT port with PVC fitting material for corrosion-resistant connections
• Clear acrylic housing allows direct visual flow reading without additional instrumentation
• Vertical inline mounting orientation for straightforward in-line installation
• Flow accuracy rated at plus or minus 6 percent

Compatibility

Designed for use with air and water lines. Suitable as an inline flow measurement device for small-bore plumbing, HVAC hydronic circuits, and water treatment systems using 1/4-inch FNPT connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician in accordance with applicable IPC or local plumbing codes. Shut off and depressurize the supply line before threading the meter into the fitting. The unit must be mounted in a vertical orientation for accurate readings. Avoid overtightening the FNPT fittings, as the acrylic housing can crack under excessive torque.
