Vortex flow meter scale advantages and disadvantages of large inventory

Abstract: the scale advantages and disadvantages of large vortex flowmeter inventory information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Vortex flowmeter is a kind of development on the basis of the principle of karman vortex street and into a new flowmeter has the international advanced level, is mainly used in industrial pipeline medium fluid flow measurement, such as a variety of media such as gas, liquid and steam, in petroleum, chemical industry, metallurgy,. More flow meter manufacturers choose model price quote you are welcome to inquire, scale advantages and disadvantages of vortex flowmeter is big inventory under article details. Vortex flowmeter is a kind of development on the basis of the principle of karman vortex street and into a new flowmeter has the international advanced level, is mainly used in industrial pipeline medium fluid flow measurement, such as a variety of media such as gas, liquid and steam, in petroleum, chemical industry, metallurgy, paper and other industries have very extensive application. But any instrument in product performance has some limitations, vortex flowmeter is no exception. Below, small make up of Chinese measuring instrument network will introduce you to the advantages and disadvantages of vortex flowmeter. 1, the vortex street flowmeter advantages ( 1) Have no moving parts, vortex flowmeter measuring element of simple structure, reliable performance, long service life. （ 2) Vortex flow meter wide measurement range. Can achieve 1:10 range than the average. （ 3) The volume flow of vortex flowmeter is not affected by measurement of body temperature, pressure, density and viscosity of the influence of thermal parameters, such as. Generally do not need to separate calibration. It can measure the rate of flow of liquid, gas or steam. （ 4) Small pressure loss caused by it. （ 5) High accuracy, repeatability of 0. 5%, and small amount of maintenance. 2, vortex street flowmeter faults ( 1) Vortex street flowmeter work condition of volume flow is not affected by measurement of body temperature, pressure, density, the influence of thermal parameters, such as but the liquid or vapor zui, mass flow measurement results should be for gas, zui measurement result should be a standard volume flow. Mass flow rate or standard volume flow must be through the fluid density conversion, changes of fluid density caused by fluid conditions must be considered. （ 2) The main factors of flow measurement error are: pipe caused by the uneven flow velocity measurement error; Can not accurately determine the working condition of fluid medium density changes; Wet saturated steam hypothesis into dry saturated steam is measured. If we do not limit or eliminate the error, the total measurement error of vortex flowmeter. （ 3) Vibration resistance is poor. External vibration can make the vortex street flowmeter measurement error, and even can't work normally. Channel high fluid velocity of vortex occurred will allow for additional vibration of the cantilever of the lower the accuracy of measurement. Big diameter effect is more apparent. （ 4) To measure the dirt medium adaptability is poor. Body of vortex flowmeter are vulnerable to dirt or been winding dirt, change of geometry size, made a great impact on the measurement accuracy. （ 5) Straight pipe demand is high. Experts pointed out that the straight section of vortex street flowmeter must assure before 20 d after 40 d, can satisfy the measurement requirements. （ 6) Temperature resistant performance is poor. Normally only vortex flowmeter measurement under 300 ℃ medium fluid flow. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
