King 7205016131W Tube Flowmeter 10 Gpm 1 Inch Fnpt

Product Description

The KING 7205016131W is a vertical-mount tube flowmeter designed for general-purpose liquid flow measurement in water-based systems. It features a 1-inch female NPT port connection and an acrylic housing that allows direct visual reading of flow rate up to 10 GPM. Maximum working pressure is rated at 125 psi. The fitting is constructed from polyvinylchloride, and the overall installed length is 10.25 inches. Plumbing and HVAC technicians use this type of meter to verify and balance flow in hydronic loops, cooling circuits, and water distribution systems where an inline visual indicator is required.

This flowmeter is suited for residential and light commercial applications involving water service lines, hydronic heating or cooling circuits, and general process water monitoring. It mounts vertically and connects directly to 1-inch NPT threaded pipe. The acrylic tube body gives a clear, unobstructed view of the float indicator, making it practical for quick field verification of flow conditions without additional instrumentation.

Key Features

• 10 GPM maximum flow capacity for water service applications
• 125 psi maximum working pressure rating
• 1-inch female NPT connection for direct threaded pipe installation
• Acrylic housing and body provide clear float visibility
• Polyvinylchloride fittings for chemical compatibility with water systems
• Vertical mounting orientation for accurate float-tube readings
• Accuracy of plus or minus 0.03 for reliable flow verification

Compatibility

Designed as a general-purpose inline tube flowmeter for water systems using 1-inch NPT threaded connections. Suitable for use with water in plumbing, hydronic, and process water circuits.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable plumbing codes including the IPC. Shut off water supply and depressurize the line before removing or installing any inline flow device. This flowmeter must be mounted in a vertical orientation with flow traveling upward through the tube for accurate readings. Inspect NPT threads and apply appropriate thread sealant before making up connections to prevent leaks under pressure.
