Abstract: The comparison information of various flowmeters for measuring media is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. 1. Electromagnetic flowmeter: (law of electromagnetic induction) to measure various acids, alkalis, salts and other corrosive liquids; various flammable and explosive media; various industrial sewage, pulp, mud, etc. Electromagnetic flowmeters cannot be used to measure gases, vapors, and liquids containing a large amount of gas. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the comparison articles of various flowmeters measuring media. 1. Electromagnetic flowmeter: (law of electromagnetic induction) to measure various acids, alkalis, salts and other corrosive liquids; various flammable and explosive media; various industrial sewage, pulp, mud, etc. Electromagnetic flowmeters cannot be used to measure gases, vapors and liquids containing a large amount of gases. They cannot be used to measure liquid media with very low conductivity, high temperature and high pressure fluids, especially pulsating flow (independent of pressure, temperature, and viscosity). Generally installed vertically, and the flow is full (5D in the front of the straight pipe section and 3D in the back). 2. Vortex flowmeter: (the principle of free oscillation of fluid) Vortex flowmeter is mainly used for flow measurement of medium fluid in industrial pipelines, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range and high precision. It is almost not affected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring the volume flow of the working condition, especially the pulsation frequency (independent of pressure, temperature, density) ), both horizontal and vertical installations are possible (there are certain requirements for the front and rear of the straight pipe section, 20D upstream and 5D downstream). 3. Turbine flowmeter: (the principle of fluid moment of momentum) Turbine flowmeters are widely used in the following measurement objects: petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, coal gas and cryogenic fluids, etc., especially for measuring pulsating flow (with Pressure, temperature, density), can only be installed horizontally (15D before the straight pipe section, generally 5D). 4. Differential pressure flowmeter: (the principle of static pressure difference of fluid) It can be used to measure the flow of liquid, gas and steam. It is the most widely used flow measuring instrument (related to pressure, temperature and density), Both horizontal and vertical installations are possible (10D at the front of the straight pipe section and 5D at the rear). 5. Coriolis force mass flowmeter: (the vibration principle of the sensor) Mass flowmeter is widely used in petrochemical and other fields, and is one of the most advanced flow measurement instruments in the world today (with pressure, temperature, viscosity, conductivity, Regardless of the flow state), both horizontal and vertical installations are possible, and the flow is full (no straight pipe section requirements). 6. Ultrasonic flowmeter: (ultrasonic pulse principle) At present, my country can only be used to measure fluids below 200 °C. Flow measurement of strong corrosive, non-conductive, radioactive and flammable and explosive media. 7. Oval gear flowmeter: (the principle of differential pressure of fluid) It is a positive displacement flowmeter, used for precise continuous or discontinuous measurement of the flow or instantaneous flow of liquid in pipelines, regardless of the relevant pressure head, independent of the Reynolds number, other The above flow meters are related to Reynolds number (related to pressure, temperature, etc.), and both horizontal and vertical installations are available (no straight pipe requirements). 8. Target flowmeter: the widest range of flowmeters, which can accurately measure the gas and liquid flow under various normal temperature, high temperature 500 degrees, low temperature -200 degrees, accurate measurement, accuracy can reach 0.2%, simple and convenient installation, extremely Easy to maintain. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Comparison of Various Flow Meters Measuring Media'
