Introduction to Vortex Flow Meter

Vortex flowmeter is a kind of flow measurement instrument designed based on the Karman vortex principle, which is also become vortex flowmeter or Karman vortex flowmeter. It is mainly used to measure the volume flow rate of gas, steam or liquid in various pipelines. Vortex flowmeter is widely used in industrial production, energy measurement, environmental protection, transportation and many other fields.

Characteristics of Vortex Flow Meter

The vortex flowmeter is characterized by high accuracy, wide measuring range, no moving parts, no mechanical wear and tear, easy maintenance, small pressure loss, and significant energy savings.

Vortex flowmeter is not applicable to low Reynolds number of cases, for high viscosity, low flow rate, the use of small diameter has limitations, the flowmeter should be installed with sufficient length of the straight section, upstream and downstream of the length of the straight section is not less than 20D and 5D, and, as far as possible, should be eliminated vibration.

The frequency of the vortices in a vortex flowmeter is not affected by temperature, pressure, viscosity, ug uban pa, and therefore has a high measurement accuracy.

Applications of Vortex Flow Meter

Vortex flowmeters are used in a fairly wide range of applications, mainly in the following areas:

• 1. Industrial production: Metallurgy, electric power, coal, chemical, petroleum and other industries.
• 2. Energy measurement: Coal, crude oil, coal bed methane, petroleum gas, natural gas and steam.
• 3. Environmental protection: Monitoring and control of emission flows of flue gases, waste liquids, effluents, etc.

Meacon vortex flow meter is a high accuracy, wide range, good stability, adaptable and widely used flow measurement instruments.
