16530 - Miller 16530 Argon/CO2 Pipeline Flowmeter with Protective Housing

Miller 16530 Heavy-Duty Flowmeter Overview

The Miller 16530 is a premium heavy-duty flowmeter engineered for precise control of Argon and CO2 shielding gases in industrial welding applications. Designed to operate at an inlet pressure of 80 PSIG, this unit is ideal for attachment to regulators or direct integration into shop pipeline installations. The core of the device features an extra-long flow tube constructed from shatter-resistant polycarbonate resin, ensuring longevity and safety in rigorous work environments. Unlike standard glass tubes that are prone to breakage, this resin construction withstands the mechanical stresses typical of busy fabrication shops.

Precision Engineering and Accuracy

Accuracy is paramount in shielding gas delivery to ensure weld quality and reduce waste. The Miller 16530 utilizes a unique, exclusive self-centering ball guide technology. In conventional flowmeters, the ball can float off-center within the tube, allowing gas to bypass the indicator and resulting in actual flow rates that can be up to two times greater than the reading indicates. Miller's design keeps the ball perfectly centered, providing accurate flow readings within five percent of the full scale, even if the flowmeter is tipped or installed at a slight angle. This ensures that the welder receives exactly the coverage required for the application.

Rugged Construction and Readability

To further enhance durability, the 16530 model comes equipped with a rugged aluminum housing that protects the flow tube on three sides. This protective shell shields the critical components from accidental impact while maintaining an unobstructed view of the flow reading. The scale itself features a high-visibility green background, designed to ease reading from a distance or in low-light conditions often found in welding bays. The unit connects via a standard 1/4-inch FNPT fitting, making it compatible with a wide range of industrial gas systems.
