Comparison of various flow meter scale measurement medium

Abstract: the comparison of flow meter scale measurement medium information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. 1. Electromagnetic flowmeter: ( Electromagnetic induction law) Measurement of all kinds of acid, alkali, salt and other corrosive liquid; All kinds of inflammable, explosive medium; All kinds of industrial wastewater, pulp, mud, etc. Electromagnetic flowmeter can not be used in measuring gas, steam and liquid contains a lot of gas. More flow meter manufacturers choose model price quote you are welcome to inquire, here are a variety of flow meter scale comparison of measured medium article details. 1. Electromagnetic flowmeter: ( Electromagnetic induction law) Measurement of all kinds of acid, alkali, salt and other corrosive liquid; All kinds of inflammable, explosive medium; All kinds of industrial wastewater, pulp, mud, etc. Electromagnetic flowmeter can not be used in measuring gas, steam and liquid contains a lot of gas. Cannot be used to measure the liquid medium conductivity is very low, cannot measure the high temperature and high pressure fluid, especially to measure pulsating flow ( Has nothing to do with the pressure, temperature, viscosity) 。 Generally installed vertically, and flow tube (full Before the straight pipe after 5 d, 3 d) 。 2. Vortex street flowmeter: ( The principle of fluid free oscillation) , vortex flowmeter is mainly used for industrial piping medium fluid flow measurement, such as gas, liquid and vapor, and other media. Is characterized by small pressure loss, wide range, high precision, working condition of the measurement volume flow is almost not affected by the fluid density, the influence of the parameters such as pressure, temperature, viscosity, especially can output pulse frequency ( Has nothing to do with the pressure, temperature, density) Installed, the horizontal and vertical can ( Straight pipe before and after a certain requirements, the upstream downstream of 20 d, 5 d) 。 3. Turbine flowmeter: ( The principle of fluid momentum) Turbine flowmeter is widely applied in the following measurement object: oil, organic liquid and inorganic liquid, liquefied gas, natural gas, coal gas and cryogenic fluid, etc. , especially to measure pulsating flow ( Related to the pressure, temperature, density) , can only be installed horizontally ( Straight pipe before 15 d, generally for 5 d) 。 4. Differential pressure type flowmeter: ( The principle of fluid static pressure) It can be used to measure the rate of flow of liquid, gas, and steam, zui widely is the application of flow measurement instrument ( Related to the pressure, temperature, density) Installed, the horizontal and vertical can ( Straight pipe before 10 d, 5 d) 。 5. The coriolis force mass flowmeter: ( The vibration of the sensor principle) Mass flowmeter is widely used in petrochemical and other fields, zui advanced in the world today is one of the flow measurement instrument ( With the pressure, temperature, viscosity, conductivity, flow state) , both the vertical and horizontal installation can, and the flow tube (full No straight pipe requirements) 。 6. Ultrasonic flowmeter: ( Ultrasonic pulse principle) At present our country can only be used to measure the fluid under 200 ℃. Strong corrosion resistance, electrical conductivity, radioactive and flammable and explosive medium flow measurement problem. Oval gear flowmeter: ( Fluid pressure differential principle) It is a kind of displacement meter, used for precise measurement for continuous and discontinuous liquid flow or instantaneous flow of pipeline, and the pressure head, has nothing to do with Reynolds number, more than other flowmeter are related to the Reynolds number ( Related to the pressure, temperature,) Installed, the horizontal and vertical can ( No straight pipe requirements) 。 Target flowmeter: wide range zui flowmeter, can accurately measure all kinds of room temperature, high temperature, low temperature - 500 degrees 200 degrees to the flow of gas, liquid, under the condition of accurate measurement, the precision can reach 0. 2%, simple and convenient installation and easy to maintain. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

The increasing consumption demand in key segments such as fork density meter manufacturer, tuning fork liquid density meter and vortex flow meter manufacturer have been driving the sales of and its derivatives worldwide.
