What are the commonly used flow meters and what are their characteristics?

1. Electromagnetic flowmeter: (law of electromagnetic induction) measures various corrosive liquids such as acids, bases, salts, etc; Various flammable and explosive media; Various industrial wastewater, pulp, mud, etc. Electromagnetic flow meters cannot be used to measure gases, vapors, and liquids containing large amounts of gas It cannot be used to measure liquid media with low conductivity, high temperature and high pressure fluids, especially pulsating flow (independent of pressure, temperature and viscosity). Generally installed vertically, with full flow in the pipe (5D in front and 3D in the back of the straight pipe section). 2. Vortex flowmeter: (principle of fluid free oscillation) Vortex flowmeter, mainly used for measuring the flow of industrial pipeline medium fluids, such as gas, liquid, vapor and other media. Its characteristics are small pressure loss, large range, high accuracy, and it is almost unaffected by parameters such as fluid density, pressure, temperature disturbance, viscosity, etc. when measuring the volumetric flow rate of working conditions. Especially, it can output pulsating frequency (independent of pressure, temperature, and density), and can be installed horizontally or vertically (with certain requirements before and after the straight pipe section, upstream 20D, downstream 5D). 3. Turbine flowmeter: (Principle of fluid momentum moment) Turbine flowmeter is widely used in the following measurement objects: petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, coal gas, and low-temperature fluids, especially for measuring pulsating flow rate (related to pressure, temperature, and

density), and can only be installed horizontally (15D before the straight pipe section, generally 5D). 4 Differential pressure flowmeter: (principle of fluid static pressure difference) It can be used to measure the flow rate of liquids, gases, and steam, and is currently the most widely used flow measurement instrument (related to pressure, temperature, and density). It can be installed horizontally or vertically (10D in front of the straight pipe section, 5D in the back). 5. Coriolis force mass flowmeter: (principle of sensor vibration) Mass flowmeter is widely used in petrochemical and other fields, and is one of the most advanced flow measurement instruments in the world today (independent of pressure, temperature, viscosity, conductivity, and flow state). It can be installed horizontally or vertically, and the flow rate is full pipe (no straight pipe section requirement). 6. Ultrasonic flowmeter: (Pulse principle of ultrasonic waves) Currently, it can only be used in China to measure fluids below 200 ℃. Flow measurement issues for highly corrosive, non-conductive, radioactive, and flammable/explosive media. 7. Elliptical gear flowmeter: (principle of fluid pressure difference) It is a volumetric flowmeter used for precise continuous or intermittent measurement of liquid flow rate or instantaneous flow rate in pipelines. It is related to the relevant pressure head and independent of the Reynolds number. All other flowmeters are related to Reynolds number (related to pressure, temperature, etc.), and can be installed horizontally or vertically (without straight pipe section requirements). 8. Target flowmeter: The widest range flowmeter that can accurately measure gas and liquid flow rates under various working condit
