Vortex Flowmeter is a new type of Flowmeter based on Karman vortex street principle, which is mainly used to measure the flow of medium fluid in industrial pipeline, such as gas, liquid, steam and so on. It is characterized by small pressure loss, large measuring range and high precision, and is almost not affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. Chongqing Vortex Flowmeter has been developed quickly since it came out because the Vortex Flowmeter has the disadvantage that other Flowmeters do not have. According to statistics, the proportion of the use of vortex Flowmeters in Japan, Europe and the United States and other prosperous countries has rebounded greatly, and has been widely used in various fields. Judging from this trend, the vortex Flowmeter will occupy a dominant position in the future flow meters, and it is the illusion of the orifice Flowmeter instead of the product. First, introduce the advantages of the vortex Flowmeter:

1. The structure is simple and stable, no movable parts, and the temporary operation is very reliable.

2. The protection is very inconvenient and the installation cost is low.

3. The sensor does not contact the medium indirectly, so it has stable performance and long service life.

4. the input pulse signal which is inversely proportional to the flow rate has no zero drift and high precision, so it is not convenient to connect with the computer.

5. the measuring scale is wide, and the measuring range ratio can reach 1:10.

6. small pressure loss, low operating cost, more energy-saving significance.

7. Within the definite Reynolds number scale, the input signal frequency is not affected by the physical sense properties and composition changes of the fluid, and the instrument coefficient is only related to the shape and size of the vortex generator. The Chongqing intelligent Flowmeter does not need to make up for measuring the volume flow of the fluid, and there is no need to re-calibrate the coefficient of the instrument after replacing the accessories.

8. wide application scale, and the flow rate of gas and liquid can be measured.

9. The verification period is 2-4 years.

Vortex flow has many advantages, and it is also suitable for flow measurement in all kinds of working conditions. There is a great deal of knowledge about the selection and equipment of vortex Flowmeter. When people choose and install vortex Flowmeters, they should focus on the following aspects:

1. Because the vortex Flowmeter is a kind of velocity Flowmeter, and the stability of the vortex is affected by the flow velocity, it has a positive request for the straight pipe section, some of which are the first 10D and the last 5D.

2. When measuring liquids, the upper velocity is limited by pressure loss and erosion phenomena, and some of them are 0.5~8m/s.

3. When measuring gas, the upper velocity is limited by the change of medium contractibility, the upper velocity is limited by Reynolds number and sensor sensitivity, and the steam is 8~25m/s.

4. Because the stress vortex Flowmeter is sensitive to vibration, the pipeline should have a definite damping method for the flow timing of the pipeline device with large vibration.

5. Because the stress vortex Flowmeter uses piezoelectric crystal as the detection sensor, it is limited by temperature, which is-40 ℃ 300 ℃.

In addition, a lot of trouble of vortex Flowmeter installation is that a long straight pipe section is needed before and after, which will improve the old equipment of the operator, and will easily be restricted by the site. However, at present, some manufacturers have been able to provide the design of external diameter reduction of the Flowmeter, which greatly reduces the demand for users to specialize in the straight pipe section of the vortex street Flowmeter, thus saving a lot of equipment for enterprises.
