B-F Flare Gas Ultrasonic Flow Meter

B-F Flare Gas Ultrasonic Flow Meter

B-F flare gas ultrasonic flowmeter adopts all-metal ultrasonic transducer. It is suitable for measurement in a variety of harsh environments. The turndown ratio is large. It can measure hydrocarbon gas, exhaust gas and other gas containing impurities and humidity.

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-F Flare Gas Ultrasonic Flow Meter

  • Large turndown ratio and wide flow velocity measurement range;
  • Suitable for multi-component metering. The gas flow meter is not affected by changes in composition.
  • Suitable for gas flow measurement with rapid changes in composition.
  • Measuring velocity and volume flow;
  • It can measure pulsating flow and can measure in both directions;
  • Measuring hydrocarbon gas;
  • Suitable for gas containing impurities, damp and dirty, corrosion resistance.
  • No routine maintenance is required.
  • It can be installed and maintained online.
  1. Wide range ratio, wide applicable flow range. Can detect small leaks.
  2. The gas flow rate in the flare system is complex and changeable, and the gas composition is often a mixture of multiple different gas sources. The measured fluid has the characteristics of complex and changeable composition, obvious pressure and temperature fluctuation, and wide flow range. Using B-F to measure this type of fluid is excellent.
  3. The B-F flowmeter has no moving parts. The probe is made of all metal material. Can withstand the corrosive environment of flare gas. Stable and durable. Low maintenance.
