King 7510212A-11 Inline Flowmeter 70 Scfh 1/4 Inch Fnpt

Product Description

The KING 7510212A-11 is a block-style inline flowmeter designed to measure gas or liquid flow rates in compressed air and water service lines. It features an acrylic housing for direct flow visualization and accepts 1/4 inch FNPT connections. Rated to a maximum working pressure of 125 psi with a flow capacity of 70 SCFH, this meter installs vertically in-line and suits both light industrial and mechanical service applications. Plumbers, HVAC technicians, and facilities maintenance professionals install this flowmeter where accurate, at-a-glance flow monitoring is required without the need for electronic instrumentation.

This flowmeter is suited for residential and light commercial applications involving compressed air or water lines. The block-style body simplifies installation in tight inline configurations. Its 1/4 inch FNPT port and PVC fittings make it compatible with standard pneumatic and fluid handling plumbing found in HVAC, compressed air distribution, and water treatment setups. Vertical mounting orientation is required for accurate operation.

Key Features

• 70 SCFH maximum flow capacity for air and water service
• 125 psi maximum working pressure rating
• 1/4 inch FNPT port with PVC fittings for standard line connections
• Acrylic housing provides clear, direct-read flow visualization

Compatibility

Designed for use with air and water service lines requiring 1/4 inch FNPT inline flowmetering at pressures up to 125 psi.

Installation Notes

This flowmeter must be installed in a vertical orientation for accurate readings. Shut off the supply line and depressurize the system fully before making any connections. Use appropriate thread sealant on FNPT connections and avoid overtightening to protect the acrylic body from cracking. Installation should comply with applicable local plumbing or mechanical codes.
