Vortex Steam Flow Meters

Applications

Vortex flow meters are designed based on the Karman vortex street principle and are suitable for measuring the volumetric and mass flow rates of superheated steam, saturated steam, and various general gases. Their applications are wide-ranging, covering various media flowing in industrial pipelines, especially in gas flow measurement scenarios where a certain level of measurement accuracy is required and the flow rate is suitable.

Vortex gas flow meters can measure a variety of gases, including but not limited to the following types:

  1. Fuel gases: coal gas, natural gas, liquefied petroleum gas
  2. Industrial gases: air, nitrogen, oxygen, argon, compressed air
  3. Chemical gases: hydrogen peroxide, chlorine, phosgene, hydrogen sulfide, sulfur dioxide, ammonia
  4. Hydrocarbon gases: methane, butane, acetylene
  5. Special gases: flue gas, biogas, carbon dioxide
  6. Others: toluene, benzene, xylene, and other volatile organic compounds
