Model 351 flowmeter Argon/Carbon Dioxide Regulator is zero-compensated for more efficient shielding gas use. This heavy duty pipeline version of Model 351 is a compact flowmeter Regulator at the price and size of most competitive flowmeters. It is designed to provide accurate and consistent flow despite wide fluctuations in pipeline pressure. This flowmeter features a durable, easy-to-read, flow tube and cover, a gaugeless brass body, large plastic knob for precise adjustments and one-piece encapsulated seat design with internal filter and PTFE Teflon seat to protect it from particulate contamination.
