B-D Pipe Segment Ultrasonic Gas Flow Meter

B-D Ultrasonic Gas Flow Meter is a pipe section flowmeter. Use mono mode. The sound channel design of the ultrasonic transducer takes into account the requirements of various working conditions. Match the rectifier of corresponding caliber. It can be used for high-precision measurement of pipe sections smaller than DN200.

Sino-Inst offers a variety of  Ultrasonic gas flow meters for flow measurement. If you have any questions, please contact our sales engineers.

Features of B-D Ultrasonic Gas Flow Meter

  • Overall explosion-proof design;
  • No moving parts, no pressure loss, reducing use and maintenance costs;
  • The starting flow rate is small. Suitable for measuring low-speed flow;
  • Large turndown ratio, turndown ratio 1:125, measuring flow rate from 0.2-25m/s;
  • The metering is not affected by the composition. Suitable for measuring multi-component gases or gases with changes in composition;
  • The influence of dust and moisture is small. Dirty gases such as coal gas and flue gas can be measured;
  • Proprietary algorithm, which can adapt to the measurement occasions with rapid changes in components, rapid changes in temperature, pressure, and humidity;
  • Can measure pulsating flow and bidirectional flow;
  1. Unique operating software design combines waveform debugging and parameter setting. Convenient on-site operation and maintenance;
  2. Unique maintenance alarm can realize early warning of maintenance time. Provide product stability.
  3. The all-metal ultrasonic transducer has strong anti-interference ability, dirt resistance and long service life.

B-D Ultrasonic Gas Flow Meter Applications

  • It is suitable for the measurement of alkanes such as natural gas, coal bed methane, mine gas, liquefied petroleum gas, methane, ethane, propane, butane, etc.;
  • It is suitable for the measurement of gas such as biogas, biological fermentation gas (water-containing impurities), and biomass fuel gas;
  • Suitable for the measurement of air, oxygen, nitrogen, argon, helium, nitrogen, and other non-corrosive gases;
  • It is suitable for the measurement of flare gas, tail gas, landfill gas, and water treatment aeration;
  • It is suitable for the measurement of helium, ammonia, acetylene, and other gases;
