详细介绍

The Gas Flow Monitor (GFM™) precisely measures flow rates of welding shielding gases using the state of the art MEMS flow sensor with OLED graphic display.

The GFM™ has 6 selectable gas settings, ARGON, Argon/ CO2 (90/10), Argon/ CO2 (80/20), Argon/ CO2 (75/25), Helium, and CO2. The GFM™ can be custom ordered and configured for additional gas mixturess.

A flow rate (5 to 255 SCFH) is digitally displayed with a 1 SCFH resolution. The accuracy of the 3% of full scale reading on the GFM™ is considerably better than conventional ball type flow meters.

The GFM™ can be installed in-line, downstream of the gas regulator for permanent installations, and is available in a battery powered configuration with a rubber cone for testing gas flow at the welding torch nozzle throughout the shop.
