The physical properties of the fluid's influence on the flow meter scale

Abstract: the physical properties of fluid to flow meter scale effect of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. In the face of the customer flow meter when the choose and buy, as a flow meter manufacturer, we will ask a series of questions, what is the density of fluid, fluid have corrosive, fluid pressure, fluid temperature, and so on, is must ask these questions? More flow meter manufacturers choose model price quote you are welcome to inquire, here is the physical properties of the fluid's influence on the flow meter scale article details. In the face of the customer flow meter when the choose and buy, as a flow meter manufacturer, we will ask a series of questions, what is the density of fluid, fluid have corrosive, fluid pressure, fluid temperature, and so on, is must ask these questions? Are said to the above and fluid physical property parameters of the related. The physical properties of the parameters on the flow characteristic of fluid affects is one of the main problems of flow meter design calculation and use. The influence degree of the physical properties of flowmeter varies depending on the working principle, at present there are some common flowmeter changyou's property: 1 density; 2 viscosity; 3 conductivity; The speed of sound; Coefficient of thermal conductivity; 6 isentropic index; 7 specific heat; Chemical corrosion; 9 scale; 10 lubricity; Phase change; 12 abrasion. Why must master the physical parameters? Master the physical parameters have what use? 1. Selection of flowmeter selection is mainly based on understanding of instrument performance and the physical properties of measured medium from two aspects. Fluid physical parameters is an important part of the measured object properties. When used at the scene, there is no lack of physical parameters for fluid control is insufficient or inaccurate and make the measurement can not meet the requirements of the instance. 2. The calculation in the design of flowmeter in flow meter design calculation, physical parameters is one of the main parameters, accurate and reliable to make the design and calculation of basic data is indispensable. 3. Use and maintenance of the fluid property change is the scene when used to generate additional error is one of the main reasons for the flow measurement, to reduce the additional measurement error, should delve into the influence of physical parameters on the flow characteristic. Some problems existing in current physical parameters instrument industry 1. Lack of online property measuring instrument, poor quality, narrow range of application in order to improve the accuracy of flow measurement, be badly in need of development of online property measuring instrument, in order to make the correction in the process of measuring online, current density and viscosity of online measuring instrument ( Transmitter) Not only technically complex, expensive, and the application range is narrow, so not a lot of popularization and application; 2. Physical parameters data accuracy is low, low confidence and do not have a unified data flow fluid physical parameters which are used for measuring data is taken from a variety of physical, chemical and engineering manuals, due to the mixed source, data inconsistencies, all kinds of different requirements for manual use object, it is difficult to meet the high accuracy of flow measurement and the need to clear the requirement of the accuracy of numerical, many fluid physical property data is not enough, or no, especially such as high parameters ( High pressure, high temperature, low temperature, high vacuum degree, etc. ) Fluid and multiple fluid ( Fluid mixture) Physical parameters, not only the confidence level is poor, or even completely lack; 3. Considering the lack of special property manual fluid physical parameters influence on measurement accuracy, foreign existing physical parameters property national standards for the minority, but for a lot of physical parameters need to compile a handbook of flow measurement for physical parameters more reality, manual data can provide a complete and unified. Especially with the popularity of computer use, physical parameters in charts can not only meet the requirements, the need to provide all kinds of formulas is convenient for use. Into abundant flow meter, thirty years brand, 30 years of professional, professional selection, professional offer, tally up experience of 30 years production practice, efforts to develop all kinds of flow metering products, according to different customer needs, requirements of different customers equipment, professional custom-made all kinds of non-standard meter products, fully in accordance with the customer to provide parameters and requirements for customers & other; Customized & throughout; , & other; * quality, user * & throughout; The light of policy, to ensure product quality long-term stability, and constantly improve to provide users with high-quality products and perfect service. To give full play to the factory of the flowmeter zui big effect, to the customers bring more convenience and benefits. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
