King 7511212B-07 Inline Flowmeter 20 Scfm 1/2 Inch Fnpt

Product Description

The KING 7511212B-07 is a block-style inline flowmeter designed for measuring gas and liquid flow rates in compressed air and water systems. Built with an acrylic housing and PVC fittings, it provides a clear visual indication of flow and handles up to 125 psi working pressure with a rated capacity of 20 SCFM. The 1/2-inch FNPT port connects directly into inline piping runs. Mounting orientation is vertical. This flowmeter is installed by HVAC technicians, plumbers, and mechanical contractors in fluid-handling and pneumatic system applications.

The 7511212B-07 is suited for residential and light commercial applications involving compressed air distribution or water flow monitoring. Its block-style body integrates into inline piping without additional manifold hardware. The FNPT connection accepts standard pipe thread fittings, making it compatible with common compressed air and water supply configurations. Accuracy is rated at 5 percent, appropriate for general flow verification and balancing tasks rather than precision metering.

Key Features

• 20 SCFM maximum flow capacity for compressed air service
• 125 psi maximum working pressure rating
• 1/2-inch FNPT port for direct inline pipe thread connection
• Acrylic housing provides visible flow indication without additional instrumentation
• Compatible with both air and water service
• Vertical mounting orientation for consistent float-tube accuracy

Compatibility

Designed for inline installation in compressed air and water piping systems using 1/2-inch FNPT connections. Suitable for air and water service as stated by the manufacturer.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician. Depressurize and isolate the line before installing or servicing the flowmeter. The unit must be mounted vertically per manufacturer orientation requirements for accurate float-tube readings. Refer to applicable plumbing codes such as the IPC for piping system requirements.
