The Victor FM157 Flowmeter Assembly (SKU: 1000-0263) is a medium-duty precision instrument designed to accurately measure and control the flow of shielding gases in industrial welding environments. Engineered by Victor, a leader in gas control technology, this unit is specifically calibrated for use with Argon and Helium, making it an essential component for MIG (GMAW) and TIG (GTAW) welding setups where gas coverage is critical to weld quality.
One of the standout features of the FM157 is its robust construction. Unlike traditional flowmeters that utilize fragile glass tubes, this assembly features a flow tube and outer cover tube made from impact-resistant Lexan. This advanced polycarbonate material offers exceptional durability, capable of withstanding the accidental knocks and drops that are common in busy fabrication shops. This design choice significantly reduces maintenance costs and downtime associated with broken flow tubes.
The device is calibrated to operate at an inlet pressure of 25 PSIG, providing a flow range of 15 to 65 SCFH for Argon and 40 to 200 SCFH for Helium. This dual-scale capability allows welders to switch between different shielding gases without needing to change hardware, provided the supply pressure is regulated correctly. The flowmeter is back-pressure compensated, meaning it maintains accurate readings even when restrictions occur downstream, such as in the torch cable or nozzle.
Installation is straightforward with a standard 1/4" NPT Male inlet connection, allowing it to be easily threaded into manifolds, pipeline drops, or compatible regulator bodies. The outlet is a standard 5/8"-18 RH Female fitting, compatible with most standard inert gas hoses. Safety is also prioritized, with the cover tube containing built-in overpressure protection to prevent catastrophic failure in the event of a pressure surge.
