The Xinya Gas Roots Flowmeter is a high-precision, highly reliable positive displacement meter designed for accurate measurement of non-corrosive gases such as natural gas, coal gas, propane, nitrogen, and carbon dioxide in closed pipelines. This series includes three main categories: the HR type (electronic single display), HRM type (mechanical single display), and HRS type (dual display). It also offers optional wireless communication modules ("-W") and prepaid control valves ("-P"), enabling remote meter reading and pay-before-use functionality. With excellent measurement accuracy, wide turndown ratio, and stable performance, the Xinya Gas Roots Flowmeter has become the preferred equipment for urban gas metering and industrial gas trade settlement.
