1. Which is more accurate, vortex flowmeter or electromagnetic flowmeter? The accuracy of vortex flowmeter and electromagnetic flowmeter depends on the testing medium and usage method, and cannot be compared. Electromagnetic flowmeter measures flow rate by cutting magnetic field lines with conductive fluid, so it can only measure water and cannot measure water with low ion content in power plants. Its measurement accuracy is better than 0.5%, with diameters ranging from 25mm to several meters. The vortex flowmeter relies on the fluid passing through a cylindrical cluster to generate Karman vortices, and the flow rate is proportional to the frequency of the vortices to obtain the flow rate. The vortex street accuracy is between 1.0% and 2.0%, with a maximum aperture of 250mm. It can measure water or other liquids, steam, and gases, and has a wider range of applications than electromagnetics.

3. Can vortex flowmeter be used for water measurement?

Vortex flowmeter can be used for measuring water inside the hood.. 1. Principle Applicability: The vortex flowmeter operates based on the Karman vortex principle. When water flows through a blocking fluid, vortices are alternately generated on both sides. By detecting the frequency of the vortex, the flow velocity and flow rate can be converted. The physical properties of water are fully compatible with this measurement method

2. In practical applications, it is commonly used in circulating water systems and cooling water monitoring in industrial fields, and can be used for tap water measurement in civilian fields, covering production and daily life scenarios

4. What is the accuracy level of the flowmeter? The accuracy classification of flow meters is mainly determined based on the maximum allowable error expressed as a percentage of the instrument (excluding the percentage sign). The higher the accuracy level, the smaller the measurement error of the instrument, that is, the higher the accuracy of the instrument.
