Premium and Standard Duty Flowmeters | MillerWelds

HD Argon/CO2 flowmeter, 80 PSIG

Heavy-Duty flowmeter models are available in two different inlet pressures ranges and wide verity of gasses and blends. They can be attached to regulators or pipeline installations. Features include an extra-long flow tube made of shatter-resistant polycarbonate resin that is accurate to within five percent of the full scale reading. Flow tubes have a unique ball guide which centers the ball in the tube and keeps it centered (competitors use a ball floating in a non-centering tube which allows the ball to float off-center resulting in greater flows than the reading indicates).

Rugged Protective Flowmeter Housing
Flow tubes are protected from accidental damage while offering unobstructed view of flow reading. Note: Protective housing available on 16530 and 16531 models only
Shatter-Resistant Multi-Scale Flow Tube
Tubes are made of shatter-resistant polycarbonate resin and feature multiple scales.
Unique Self-Centering Ball Guide
Miller-Smith’s exclusive ball-centering flow tube provides accurate flow readings even if the tube is tipped. This ensures good weld quality and gas savings. Non self-centering flow tube ball tends to float off center. Actual gas flow can be up to 2-1/2 times greater than is indicated. Note: Self-centering ball guide available on 16530 and 16531 models only
