Vortex Flow Meters

Vortex flow meter, also called Vortex shedding flow meter. Vortex Flow Meter is suitable for flow measurement of steam and various liquids and gases.

The vortex flowmeter is a volume flowmeter that measures the volume flow of gas, steam or liquid, the volume flow of standard conditions or the mass flow of gas, steam or liquid based on the Karman vortex principle. When the fluid flows through the dust collector rod of the vortex flowmeter, a vortex is formed. The frequency of vortex shedding is proportional to the fluid velocity. Temperature and pressure compensation can be configured.

Vortex Flow Meter Applications

The vortex flowmeter is mainly used in the flow measurement of industrial pipeline medium fluid. The medium can be gas, liquid, steam, etc. The main scope of action includes:

• During industrial production, such as metallurgy, coal, electric power, chemical, pharmaceutical, environmental protection and other manufacturing;
• Energy measurement. Including the scientific measurement of primary and secondary energy. Such as coal, petroleum gas, natural gas, etc., to achieve energy saving and reduce consumption;
• Environmental protection engineering. Including flow measurement of flue gas, sewage, etc.;
• Transportation. Including pipeline transportation for control, distribution and scheduling, and better economic accounting through measurement results.

Vortex Flow Meter Working Principle

Vortex flowmeter is a speed-type flowmeter produced according to karman’s vortex principle,
which can be used for the measurement and measurement of conventional gas, steam and
liquid.

Vortex flow sensor has high precision and wide range ratio, no moving parts in use, which can
improve mechanical stability and reduce maintenance.Vortex flowmeter is almost not affected by the temperature, pressure and composition of medium when measuring the volume of working condition.

Therefore, it is convenient to calibrate the instrument, so vortex street flow sensor is widely used in production and life.

When a trigonal column vortex generator is set in the fluid, regular vortices are generated alternately on both sides of the vortex generator, which is called Carmen vortex.

The vortex columns are arranged asymmetrically downstream of the vortex generator. Vortex flowmeter is produced according to this principle.

Vortexes are generated by generating bodies and the number of vortexes is detected by high-sensitivity sensors. In a certain range, the number of vortexes generated is proportional to the flow rate.

In vortex flowmeter, the relationship between flow rate and the number of vortexes generated
can be expressed by the following formula：

Q：Operating volume flow of the measured medium. The unit is m3/h。
F：Frequency of the number of vortices produced by the generating body. The unit is Hz.
K：Refers to the calculated or calibrated flow coefficient. It represents how many frequency signals per cube. the coefficient is usually obtained by calibration.

The formula of standard table method calibration coefficient K:

The formula can also be used for flow correction.

Vortex Flow Meter Price

Price is always a topic of concern. Different types of vortex flowmeters can be found online, and the prices of different vortex flowmeter manufacturers are not consistent. The final quotation is still subject to the actual working conditions on site.

Vortex flow meters have different prices due to different calibers, different materials, different media, and different functions! The price list of vortex flowmeter is attached below for reference.
