The spiral vortex flowmeter is a new type of gas flow meter developed by our company with leading domestic level. This series of instruments integrates flow, temperature and pressure detection functions, and can automatically compensate for temperature, pressure and compression factors. It is an ideal instrument for gas measurement in coal, petroleum, chemical, electric power, metallurgy and urban gas supply industries.
