1. What is the difference between vortex flowmeter and vortex swirl flowmeter? There are significant differences in the design principles and application fields between vortex flowmeter and vortex swirl flowmeter. The vortex flowmeter is based on the Karman vortex principle and is a flow measurement device with no moving parts. It is suitable for monitoring the flow of various fluids in industrial pipelines, including but not limited to gases, liquids, and vapors. The characteristics of this flowmeter are low pressure loss, wide range, and high accuracy. Moreover, its performance is almost unaffected by parameters such as fluid density, pressure, temperature, and viscosity when measuring volumetric flow under attitude disturbance conditions. The vortex swirl flowmeter adopts microprocessing technology, which has powerful functions, wide flow range, simple operation and maintenance, and convenient installation process. Its main technical indicators have reached the advanced level of similar international products, and are widely used in gas metering in industries such as petroleum, chemical, power, metallurgy, and coal. 2. What is the difference between a vortex flowmeter and a vortex swirl flowmeter?
The difference between a vortex flowmeter and a vortex swirl flowmeter mainly lies in their definitions.
. Vortex flowmeter: It is a pure source flowmeter developed and produced based on the Karman vortex principle, mainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, vapors, and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. wh_600x400.jpg)
3. What are the commonly used flow meters in chemical industry sites?
According to the widespread application of flow meters (in the market, cost-effectiveness is generally considered), the mainstream flow meters include the following:
1. Vortex flow meter: the most widely used, accurate, sensitive, and inexpensive, especially for steam flow. In recent years, the integrated vortex flow meter with voltage stabilization and compensation has almost become dominant, but its disadvantage is that it is not shock resistant;
;2、 Electromagnetic flowmeter: used for conductive liquid materials and widely used in factories. It is corrosion-resistant, accurate, sensitive, and has a low failure rate. The disadvantage is that the price is still relatively high, especially for imported brands, which can easily cost over 10000 yuan;
3、 Spiral vortex flowmeter: Similar in appearance to vortex street, but with a different measurement principle. On a small diameter, it has a wide measurement range, better sensitivity than vortex street, weak seismic resistance, and cannot measure dirty media;
3、 Turbine flowmeter: For liquid turbines, the diameter can be made very small, sensitive, and inexp
