美国GFM气体流量计
美国CWT气体流量计 Gas Flow monitor
   Computer Weld Technology's Gas Flow Monitor (GFM™) precisely measures flow rates of welding gasses. The GFM can be used for Argon, Helium, CO2 or any mixed inert welding gas. A flow rate (5 to 255 SCFH) is digitally displayed with a 1 SCFH resolution. The accuracy if the 3% of full scale reading in the GFM is considerably better than conventional ball type flow meters. The GFM can be install in-line down stream of the gas regulator for permanent installations. The unit is also available in a battery powered configuration with a rubber cone for testing gas flow at the welding torch nozzle.
