Abstract: how to solve the electromagnetic flow meter scale measurement have larger bubble liquid information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. 【 Introduction 】 The flow of electromagnetic flowmeter is commonly used in industrial measurement instrument, has been widely applied because so often there will be a customer put forward the problems in use process. Here we talk about electromagnetic flowmeter in measuring the liquid fluid have larger bubble solution. More flow meter manufacturers choose model price quote you are welcome to inquire, here is how to solve the electromagnetic flow meter scale measurement have larger bubble liquid article details. 【 Introduction 】 The flow of electromagnetic flowmeter is commonly used in industrial measurement instrument, has been widely applied because so often there will be a customer put forward the problems in use process. Here we will talk about the electromagnetic flow meter in measuring the liquid fluid have larger bubble solution. Why other customers mentioned electromagnetic flowmeter with lining, we will come up from the principle of electromagnetic flowmeter to answer the question. Electromagnetic flowmeter will appear in the process of measuring the liquid has a lot of bubble phenomenon, which often leads to appear flowmeter measurement error, affect the use. General after electromagnetic flowmeter measurement of fluid will contain a lot of bubbles, and if these bubbles distribution more uniform will not affect measurement, but once the bubble become bigger, was grazed electrode can cover the entire electrode, make traffic signal input circuit transient open circuit, lead to shake the output signal. How to determine the electromagnetic flowmeter measurement error is caused by the bubbles in the liquid being measured? This happens and how to deal with? We make a brief introduction. When there is shaking measurements, immediately cut off the magnetic field excitation loop current, if the instrument is still have display and unstable, that is mostly caused by bubble effect. In determining a lot of bubble is affect the electromagnetic flowmeter measurement result to find relevant solution, if the judge is caused by a large number of bubbles into the liquid installation location, such as electromagnetic flowmeter in piping highs and storage gas inhalation of air flow meter or the outside world shaking, change the installation location is zui effective solution, but a lot of application is large diameter or installation position is not easy to change, the recommendations in the electromagnetic flow meter installed upstream gas collecting bag and exhaust valve, remove excess gas, reduce the influence factors of the result of the measurement, to ensure the accuracy of the measurement. Why about electromagnetic flowmeter lining, this should speak of from the principle of electromagnetic flowmeter. Electromagnetic flowmeter generally has a set of coil and two electrodes, the role of the coil is an electric field is put in the fluid, the flow of conducting liquid is equivalent to a conductor, according to Faraday's law of electromagnetic induction when conductor cutting lines of magnetic force produces a corresponding electromotive force is proportional to the speed, the effect of electrode is measuring the induced electromotive force, so the measuring tube only electrode is connected to the conductive liquid, other part is lined with, to ensure the insulation, electromagnetic flowmeter can work normally. If there is a magnetic field the metal pipe is in contact with the liquid phase, electromagnetic flowmeter and the short circuit between the conductive liquid and metal, there will be a conductive, potential guide will go make electromagnetic flowmeter cannot measure the electric potential. So the interior of the electromagnetic flowmeter are lining. When measuring the flow conductivity of liquid with speed V through the perpendicular to the flow direction of magnetic field, the flow of the liquid conductivity sense if a voltage is proportional to the average flow velocity, the induced voltage signal by two or more direct contact with the liquid electrode pick, and through the cable to the converter by intelligent processing, then the LCD display or converted into a standard signal 4 ~ 20 ma output and 0-1 KHZ. In this way, the electromagnetic flowmeter can measure the conductive fluid flow. Electromagnetic flowmeter can measure the rate of flow of conducting liquid, so should have the lining inside. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
