These five factors directly lead to the measurement error of the electromagnetic flow meter

Abstract: These five factors directly lead to the measurement error of the electromagnetic flowmeter. The information is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Abstract: The electromagnetic flowmeter is developed through Ferrari's electromagnetic induction principle, so its advantages are also effectively inherited, but the disadvantage is that it will be subject to external electromagnetic interference. If these external factors are not effectively dealt with during installation. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the article that these five factors directly lead to the measurement error of the electromagnetic flowmeter. The electromagnetic flowmeter is developed through Ferrari's electromagnetic induction principle, so its advantages are also effectively inherited, but the disadvantage is that it will be subject to external electromagnetic interference. If these external factors are not effectively handled during installation, it is easy to cause electromagnetic interference. The flowmeter has an error in the measurement. Below we will summarize five factors that mainly affect the error of the electromagnetic flowmeter 1. The liquid in the measurement pipeline is full. This phenomenon is mainly due to insufficient back pressure in the pipeline or poor installation of the sensor of the flowmeter. The pipeline is not full Depending on the state of the pipe, the corresponding fault will also have different performances depending on the degree of underfill. ①. When a small amount of gas is distributed in a stratified flow or wavy flow in the pipeline, the measurement results may not match the results; ②. When the fluid is In the case of bubble flow or plug flow, in addition to the fact that the measurement results are inconsistent with the actual situation, it will also cause the measurement data of the meter to fluctuate because the bubbles flow through the instrument sensor instantly covering the electrode surface; ③. If it increases, it means that the state of the liquid is not full, and the measurement data of the instrument will fluctuate. There will be over-full scale phenomenon. This kind of fault is mainly caused by the user's inaccurate estimation of the flow range of himself when selecting the model; 2. The measurement liquid contains solids. When the measurement liquid contains solids such as powder, particles or other fibers Generally, the following faults are exhibited: ①, the flowmeter in the pipeline is noisy; ②, the electrode surface is contaminated; ③, the conductive deposition layer or insulating deposition layer in the pipeline covers the electrode performance or lining; ④, the instrument lining is worn, or a deposition layer appears 3. Liquids that are easy to crystallize and some liquids that are easy to crystallize can be measured with an electromagnetic flowmeter when the temperature is normal, but the premise is that the pipeline has good heat tracing performance, but large Part of the situation is that the measuring tube of the electromagnetic flowmeter sensor is difficult to keep the temperature constant once due to the temperature drop. The liquid will crystallize and cover the surface of the pipe, resulting in instrument failure Ring, users do not need to worry about this kind of problem after purchasing, as long as the grounding of the instrument is done. There are certain requirements for the conductivity of the liquid must be≥5μs/cm, when the conductivity of the liquid is less than this lower limit, the measurement data of the instrument will also fluctuate. Summary: From the above faults, it can be concluded that most of the faults are effective in the selection and installation stage Therefore, after purchasing the instrument, users are advised to take as much time as possible to read the relevant installation and use operations of the instrument, so as to avoid malfunctions due to incorrect installation, which may seriously damage the instrument. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
