The Gas Turbine Flowmeter is a high-precision, highly reliable velocity-type flow measurement instrument. It offers excellent performance under both low and high pressures and features explosion-proof design, making it ideal for accurate measurement of high-flow gases such as natural gas. The flowmeter consists of a metering module (base) and a display module (head), with optional wireless communication and IC card prepaid control valve for flexible user applications. We provide various accuracy levels and performance models, widely used in industrial and urban gas measurement.
