Rental gas flow meters include TVC’s Gas Flow Meter 2 (GFM2) and Nozzle Flow Meter 3 (NFM3) for accurate welding gas flow measurement. GFM2 The Gas Flow Meter 2 (GFM2) can be used at the torch nozzle or downstream of the regulator to measure all shielding gases and gas mixes. Peak gas flow displays for gas consumption analysis and flow results. Data logging facility captures pressure data, temperature, and surge data. Connects to any TVC welding data logging system, providing a permanent record of gas flow measurements. NFM3
