King 7205020131W Tube Flowmeter 40 Gpm 1.5 Inch Mnpt

Product Description

The KING 7205020131W is a vertical-mount tube flowmeter designed to measure liquid flow rates in general-purpose plumbing and fluid-handling systems. Built with an acrylic housing and acrylic body, this meter provides a clear visual reading of flow rates up to 40 GPM. The 1.5-inch MNPT connection makes installation straightforward on standard pipe runs. It handles a maximum working pressure of 125 psi, making it suitable for a wide range of low-to-medium-pressure water systems. Plumbers, pipefitters, and mechanical contractors install this type of meter where real-time flow visibility is required without electronic instrumentation.

The 7205020131W is suited for residential and light commercial water systems where monitoring flow is part of routine system balancing or diagnostics. Its general-purpose acrylic construction is intended for use with water. The vertical mounting orientation is a fixed design requirement and must be observed during installation to ensure accurate readings. PVC fittings are included as part of the connection assembly.

Key Features

• Clear acrylic body allows direct visual reading of flow rate without tools or meters
• Measures flow rates up to 40 GPM with an accuracy of plus or minus 0.06
• 1.5-inch MNPT connection fits standard NPT-threaded pipe and fittings
• Rated to 125 psi maximum working pressure
• Vertical mounting orientation ensures accurate float-tube readings
• PVC fittings included for connection to system piping

Compatibility

Designed for use with water in general-purpose flow measurement applications. Connections are sized for 1.5-inch NPT-threaded pipe assemblies.

Installation Notes

A licensed plumber or pipefitter should install this flowmeter in compliance with applicable IPC requirements. Shut off the water supply and relieve system pressure completely before making any connections. This meter must be mounted in a vertical orientation — horizontal installation will produce inaccurate readings. The acrylic body is not rated for elevated temperatures or chemically aggressive fluids; do not exceed the 125 psi pressure rating.
