Gas Roots Flow Meter

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.

Product Advantages

  • Unique structural design:With a structure protected by proprietary intellectual property rights, it is convenient to assemble and has stable performance.
  • Wide turndown ratio and low starting flow rate: NThe turndown ratio can reach up to 160:1, with a starting flow rate of less than 0.02 cubic meters per hour.
  • Flexible installation:Supports vertical, left-to-right, and right-to-left installation. The meter head can be rotated 350° for easy reading.
  • High-precision manufacturing:High part commonality, strong interchangeability, good repeatability, and long service life.
  • No straight pipe section requirement:No need for straight pipe sections before and after, can be used in narrow spaces.
  • Multi-parameter detection and compensation:Built-in high-precision temperature and pressure sensors, as well as a volume correction device, to achieve automatic compensation and compressibility factor correction.
  • Humanized display:High-contrast LCD display shows multiple operating parameters with Chinese prompts.
  • Safety protection:Explosion-proof grade ExiaCT4 Ga, protection level IP66.
  • Intelligent control valve:EZero-pressure-loss ball valve design with a patented opening mechanism to ensure reliable opening under medium and high pressure.
  • Large flow applications:Supports a maximum one-time gas purchase volume of up to 100 million m³, meeting the needs of industrial-grade users.
