Electromagnetic flow meter scale with the combination of ultrasonic flow meter scale of the meter

Abstract: the amount of electromagnetic flow meter scale and ultrasonic flowmeter scale instrument is the combination of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Used in petroleum, chemical industry, water meter zui area, zui for common ultrasonic flowmeter and electromagnetic flowmeter, why these two kinds of instrument will be preferred widely used? Let's analyze their main advantage. 1. Applications. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the amount of electromagnetic flow meter scale and ultrasonic flowmeter scale instrument is the combination of the article details. Used in petroleum, chemical industry, water meter zui area, zui for common ultrasonic flowmeter and electromagnetic flowmeter, why these two kinds of instrument will be preferred widely used? Let's analyze their main advantage. 1. A wide scope of application. Electromagnetic flowmeter can measure all kinds of acid and alkali liquid, sewage, paper pulp, such as conductive medium, and non-conductive ultrapure water, pure water, water and other non conductive liquid medium can be measured with ultrasonic flowmeter, so these two kinds of instrument can measure almost all common liquid after combination. 2. High precision measurement. In terms of the flow measurement precision is higher, so to speak, the better, these two instruments are very good in terms of accuracy, precision of conventional one. 0, slightly higher requirements to 0. 5, zui high can reach 0. 3, even zero. The precision of 2, at present in all kinds of flow measuring performance is very good. 3. Shine without loss of pressure flow components. Both electromagnetic flowmeter and ultrasonic flowmeter nozzle internal almost have no spare parts, so will not cause obstacles to medium, there would be no pressure loss. But electromagnetic flowmeter is limited by some of the ultrahigh pressure situations, then can use the clip type ultrasonic flowmeter, pressure will not have any influence on the flow measurement. 4. Easy installation. In general industrial field flow is measured in flange butt, inconvenience destroy existing pipelines can use clamp installed outside, very convenient. 5. High cost performance. In addition to require high precision, the price of this two kinds of instrument are populist, can accept it. That two kinds of instrument is not all, of course, advantages, some disadvantages also limit its wider use in more areas, such as ultra high temperature circumstances, the two instruments are underperforming. We look forward to the breakthrough of new materials and new technology, to make them more superior. Error of the electromagnetic flowmeter applied in a variety of causes, such as fluid composition, fluid conductivity, electromagnetic flowmeter lining dirt, etc. Electromagnetic flowmeter is based on the principle of Faraday's law of electromagnetic induction to work, has the conductive properties of the conductor in magnetic field, cutting lines of magnetic force exercise on it, will produce inductive electromotive force, downstream direction according to the right-hand rule. Commonly so the applications of electromagnetic flowmeter, the electrical conductivity of the fluid has certain requirements, application process with 5 us/cm as the dividing line. Electromagnetic flowmeter and ultrasonic flowmeter belong to speed meter, all the accuracy of the affected factors include: flocculant fluid flow ( Fluid is uniformly distributed) , scale inside lining. 1, fluid flocculant error caused by the flow of liquid velocity V for axisymmetric distribution in the pipe, and in the uniform magnetic field, flow meter with the size of the electrode electromotive force generated by the fluid velocity distribution has nothing to do, is proportional to the average flow velocity of fluid, or the electrode induction electromotive force is generated by the different, so, must choose fluid velocity turbulence as far as possible little electromagnetic flowmeter measurement section installation, avoid unnecessary errors. 2, error caused by the lining inside the scale of enterprise in chemical industry, water treatment, which is usually water meters, we often see the wall to a scale or chemical sludge layer, don't look down upon this thin layer, it can change the electromotive force of electromagnetic flowmeter deviation, thus having zero dislocation. So we often see some sewage treatment plants, in order to improve the measuring accuracy, often go to clean the electrode of insertion electromagnetic flowmeter. For now, electromagnetic flowmeter in flow measurement and testing system of energy-saving industry or the role of a dominant market, along with the electronic chip technology and improving the efficiency of computing, has gradually replaced by ultrasonic flowmeter. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
