Intelligent Gas Roots Flowmeter
The Intelligent Gas Roots Flowmeter is a positive displacement metering instrument that measures gas volume by counting the rotations of a pair of figure-8 shaped roots rotors within the metering chamber. It features high measurement accuracy and excellent stability, making it suitable for trade metering of medium to high-pressure gases such as natural gas, coal gas, and propane. This instrument is widely used in high-precision metering scenarios across various fields including urban gas transmission and distribution, and petrochemical industries.
