Overview
NST880GC1-RS Thermal Gas Flow Meter Introduction: The thermal gas mass flow meter is an instrument that uses the principle of thermal conduction to measure fluid flow. This instrument uses the constant temperature difference method to accurately measure the gas mass flow rate. A monitoring instrument that can measure the mass flow rate of air, nitrogen, hydrogen, oxygen, chlorine, natural gas, coal gas, flue gas, biogas, and other gases flowing in pipelines. Due to its diverse and flexible structural forms, it can meet the different needs of the usage site. Especially with plug-in flow meters, the most difficult flow measurement with large pipe diameters and low flow rates has become simpler.
