According to the method of measurement points of different flow meter scale is introduced

Abstract: according to the method of measurement points of the introduction of different flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Fluid flow meter classification kinetic parameters. Such as flow rate, the momentum is directly related to traffic. Therefore, the various physical effects of these parameters. As the flow measurement of physical basis. At present, various types of flowmeter has cast people use, its measurement. More flow meter manufacturers choose model price quote you are welcome to inquire, here is according to the method of measurement points of different articles about the details of the flow meter scale. Fluid flow meter classification kinetic parameters. Such as flow rate, the momentum is directly related to traffic. Therefore, the various physical effects of these parameters. As the flow measurement of physical basis. At present, various types of flowmeter has cast people use, its measuring principle, structure characteristics, applicable scope and method of use each are not identical, so its classification can be divided according to different principles. So far did not have a unified classification method, according to measurement the measuring instrument of shunt according to measurement generally can be divided into volume method, the velocity method ( The velocity law) And three kinds of mass flow rate method. A volumetric method volume method refers to the container with a standard volume has continuously for flow measurement. And the unit ( Or a) Time measurement method of standard volume number to calculate the flow. This method of measurement by flow state shape ring is smaller. Thus is suitable for measuring high viscosity, low Reynolds number flow. But unfavorable for measuring high temperature and high pressure and smudgy medium flow. The upper limit of the flow measurement is smaller. Typical instrument have oval gear flowmeter, waist wheel flowmeter, scraper flowmeter, etc. B velocity velocity method refers to according to the average flow velocity on the pipe cross section method to calculate the flow. All sorts of physical phenomena are related to the flow rate can be used to measure flow rate. If it were measured by flow volume density. Mass flow rate can be got. In the velocity flow meter. The throttle flowmeter has a long history. Technology zui to mature. Is zui widely applied in industrial production and scientific experiment of a meter. Also belong to the velocity measurement of flow meter and rotor flowmeter, turbine flowmeter, electromagnetic flowmeter, ultrasonic flowmeter, etc. Because of this method is to use the average flow velocity to calculate flow rate, so much affected by pipeline conditions. Such as Reynolds number, eddy current and sectional velocity distribution asymmetry will bring measurement error. But this measuring method has a wide use conditions. Can be used for high temperature and high pressure fluid measurement. Some instruments can also be suitable for measuring the smudgy medium flow. The current velocity method is adopted to improve the flow measurement instrument has a wide application in industry. C mass flow method whether volume method. Or velocity method. Must be given the density of the fluid can be mass flow. Fluid density and fluid state parameter ( Refund degree, stress) The influence of. This inevitably brings to the mass flow rate measurement error. One way to solve this problem is the measurement volume of fluid flow and density or according to the measurement of fluid pressure, temperature and so on the change of state parameters on the fluid density to compensate. But the more ideal method is direct measurement of mass flow rate of the fluid. This method is the physical basis of survey and fluid quality related physical quantities ( Such as momentum, momentum, etc. ) 。 Thus mass flow rate can be obtained directly. This method has nothing to do with the composition and parameter of the fluid. Has the obvious superiority. But the production of this kind of flowmeter are more complex. The price is expensive. Which limit their application. Flow is a dynamic quantity. The measurement process and fluid flow, fluid physical properties, fluid conditions, the length of the straight pipe before and after the flow meter and so on. So to determine the flow measurement method, choose flow meter, must comprehensively consider the effect of the above factors. To achieve the ideal measurement requirements. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
