What is the difference between vortex flowmeter and electromagnetic flowmeter? There are significant differences between vortex flowmeters and electromagnetic flowmeters in terms of principles, measured substances, and application ranges. 1. Principle: A vortex flowmeter is based on inserting an object (such as a slug) into a fluid to generate a vortex, and calculating the flow rate by measuring the frequency of the vortex. The electromagnetic flowmeter is based on Faradays law of electromagnetic induction, which states that when a conductor moves in a magnetic field, an electromotive force is generated in the conductor, resulting in an electric current. In an electromagnetic flowmeter, the conductor is the fluid. When the fluid moves in a magnetic field, an electromotive force is generated. By measuring this electromotive force, the flow rate of the fluid can be measured. 2. Measurement substance: Vortex flowmeters can measure substances such as liquids, gases, and vapors, and have a relatively wide range of applications. Electromagnetic flowmeters are mainly used for conductive liquids such as water, acidic and alkaline liquids, and cannot be applied to gases, vapors, and liquids containing large bubbles. 3. Measurement range: The measurement range of vortex flowmeters is usually wide and the pressure loss is relatively small. The measurement range of electromagnetic flow meters is relatively narrow, especially at low Reynolds numbers, and the accuracy of the measurement will be affected.
4. Structure and price: The structure of vortex flow meters is relatively simple and sturdy, and the price is relatively low.

Hello, KNKE, an American imported flowmeter manufacturer, is pleased to answer your question.
. The following is an introduction to the differences between electromagnetic flow meters and vortex flow meters.Firstly, the principles are different: electromagnetic flow meters are based on the fundamental law of Faraday currents magnetic effect. Potential flow lasers cut magnetic induction lines to create a potential difference to distinguish the total flow size, while vortex flow meters insert a rotor into the potential flow to create a Lenny vortex, and measure the total flow size based on the frequency of the measured vortex.
. Secondly, the measured substances are different: Electromagnetic flow meters, due to their key principle, measure the total flow rate of conductive liquids such as water. Vortex flow meters can measure liquids, gases, vapors, etc., and have a wider range of applications than electromagnetic flow meters. The standard that must be considered when measuring total flow with a vortex flowmeter is that the initial pipeline flow resistance is between 2 * 10 ^ 4-2 * 10 ^ 7, and if it exceeds this range, the aging rate will decrease. The water flow rate of the second most important liquid in the imported electromagnetic flowmeter of Konko must be within the required range. Different specifications have different water flow regulati
