1. What are the differences between electromagnetic flowmeter and vortex flowmeter?
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 the accuracy decreases beyond this range. 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 regulations. When the measured substance is gas, the water flow rate limit should be less than 60m/S, for steam, it should be less than 70m/S, and for liquid, it should be less than 4m/S. It can be used for gas-solid and solid-liquid two-phase flow containing dispersed and symmetrical solid particles
2, N2 radon gas, gas, liquefied gas, water, and liquids such as automotive gasoline, ethanol, benzene, etc.
Thirdly, the diameter of the electromagnetic flowmeter pipeline ranges from DN6 to DN1200, and only plug-in vortex flowmeters are used above DN300.
. 4. Material temperature. Electromagnetic flowmeter is a steam flowmeter used to measure conductive liquids, but it is not suitable for high temperatures. Relatively speaking, vortex streets have high practicality and can measure both liquid and gas. They also have a wide range of temperature integration and can measure high-temperature liquids and gases.Fifth, the accuracy is different: the measurement accuracy of electromagnetic flowmeter is 0.5 level, and the vortex street is generally 1.5 level accuracy.
. Whether it is an electromagnetic flowmeter or a vortex flowmeter, they have their own application characteristics and features. Only by fully understanding the characteristics of the machine equipment and selecting a suitable steam flowmeter that is necessary for oneself on the spot can it be considered suitable. I hope my answer is helpful to you.
