Introduction
Intelligent procession vortex flowmeter is a new type of gas flow meter developed by our company, which has the leading level in China. The flowmeter integrates the functions of flow, temperature and pressure detection, and can automatically compensate the temperature, pressure and compression factors. It is an ideal instrument for gas metering in petroleum, chemical industry,electric power, metallurgy and other industries.
