King 7510212A-15 Inline Flowmeter 180 Scfh 1/4 Inch Fnpt

Product Description

The KING 7510212A-15 is a block-style inline flowmeter designed to measure gas or liquid flow in compressed air and water service lines. Built with an acrylic housing and PVC fittings, it provides a clear visual read of flow rate up to 180 SCFH at a maximum working pressure of 125 psi. The 1/4-inch FNPT port connects directly into an inline installation without additional adapters in most standard configurations. This meter is installed by HVAC technicians, plumbers, and industrial service professionals who need a simple, reliable flow indication in low-pressure pneumatic or fluid systems.

This flowmeter is suited for residential and light commercial applications where monitoring air or water flow is required inline with existing piping. The vertical mounting orientation and block-style body allow for compact placement in tight service runs. It is commonly used in compressed air distribution, water treatment lines, and similar low-pressure utility systems where visual flow confirmation is needed during commissioning or routine service checks.

Key Features

• 180 SCFH maximum flow rate for compressed air and water service
• 125 psi maximum working pressure rating
• 1/4-inch FNPT port for direct inline pipe connection
• Acrylic housing and body for clear visual flow indication
• PVC fittings compatible with standard low-pressure piping
• Plus or minus 6 percent accuracy for general flow monitoring
• Vertical mounting orientation with inline block-style body

Compatibility

Designed for use with air and water service lines requiring inline flow measurement at 1/4-inch FNPT connections up to 125 psi working pressure.

Installation Notes

This flowmeter must be installed in a vertical orientation for accurate readings. Depressurize and isolate the service line completely before installing or removing the meter. Use thread sealant appropriate for the service fluid on all FNPT connections. Acrylic housings are sensitive to overtightening — hand-tighten fittings and apply only minimal additional torque to seat connections without cracking the body.
