Difference between rotary vortex flowmeter and vortex street flowmeter

Vortex flowmeter and vortex flowmeter, both are widely used in the field of industrial automation.

Vortex flow meter is a kind of velocity type flow meter, has a wide range of uses. Can be liquid, steam and most of the gas flow measurement, measurement and control. Widely used in petroleum, chemical, textile, metallurgy, food, paper, pharmaceutical, energy and other industries.

Rotary vortex flowmeter is a pressure, temperature, flow sensor in one, directly display the volume of the medium in the standard state of the flowmeter. It is through the internal temperature sensor, pressure sensor and flow sensor detection of the corresponding parameters to achieve the measurement of the standard flow rate of gas media, widely used in petroleum, chemical industry, metallurgy, city gas transmission and distribution network and other areas of gas measurement.


The following Xiao Ao to give you an introduction to the difference between the vortex flow meter and vortex flow meter

1 Structure is different
Vortex flowmeter and vortex flowmeter generator are immovable parts, usually called vortex generator, but the two vortex generator is different, vortex generator is a triangular column type, vortex generator into the vortex is similar to the turbine impeller.

2 Measuring principle is different

Vortex flow meter principle is set in the fluid triangular column vortex generator, gas flow through the vortex generator, from both sides of the alternating vortex generated by the regular vortex, this vortex is known as Carmen vortex, through the measurement of vortex occurring in the frequency to calculate the measured media flow.

Spin into the vortex flowmeter measurement principle is that when the fluid through the vortex generator composed of spiral blades, the fluid is forced to rotate around the generator axis violently, the formation of vortex. When the fluid enters the diffusion section, the vortex flow by the role of reflux, began to make the second rotation, the formation of gyroscopic vortex into the phenomenon. Both are vortex, vortex flowmeter vortex is produced alternately on both sides, the vortex into the vortex flowmeter is gyroscopic.

3 The measured medium is different

Vortex flowmeter can measure gas, liquid and steam, rotary vortex flowmeter can only measure gas.

4 Measuring pipe diameter

Vortex flowmeter measuring pipe diameter range than the rotary vortex flowmeter pipe diameter. The same diameter measurement of gas flow range is different, according to the actual application of the site to choose which flowmeter is more suitable.
