The Reasons and Solutions for the Display Fluctuation of Electromagnetic Flow Meters

Abstract: The reason for the fluctuation of the electromagnetic flowmeter meter and the information on the treatment method are provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Guide: In the process of using the electromagnetic flowmeter, some customers encounter fluctuations in the numerical value of the electromagnetic flowmeter head (integrated or split), sometimes with negative values, and sometimes with positive values ​​skipping the meter. Now let's talk about the electromagnetic flowmeter display number. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the reason for the fluctuation of the electromagnetic flowmeter meter and the treatment method. Guide: In the process of using the electromagnetic flowmeter, some customers encounter fluctuations in the numerical value of the electromagnetic flowmeter head (integrated or split), sometimes with negative values, and sometimes with positive values ​​skipping the meter. Next, let's talk about the direct reason for the fluctuation of the electromagnetic flowmeter's displayed value. The instantaneous flow rate in the flowmeter is unstable. This situation may be caused by various reasons. The elimination method can be used in the field to find the flow rate instability. reason. The direct reason for the fluctuation of the electromagnetic flowmeter is that the instantaneous flow in the flowmeter is unstable. The electromagnetic flowmeter is an accurate instrument, and it can be accurately sensed and displayed when the flow changes slightly. There are many reasons for the unstable instantaneous flow. For example, the straight pipe sections before and after the electromagnetic flowmeter do not meet the requirements, the medium is not clean or the flowmeter is not equipped with a filter, the medium itself is turbulent or the pressure is unstable, and the actual flow in the pipeline exceeds The flowmeter itself can measure the flow range and the quality of the flowmeter itself. The reason for the fluctuation of the electromagnetic flowmeter is not only that the instantaneous flow is unstable, but during the commissioning period, due to the good environmental conditions, the flowmeter works normally, and it is often easy to neglect the installation conditions at this time. In this case, once the environmental conditions change, new interference sources appear during operation, which will interfere with the normal operation of the instrument, and the output signal of the flowmeter will fluctuate. The above is only a part of the reason why the displayed value of the electromagnetic flowmeter jumps, and the possible reasons are as follows: 1. The installation position is incorrect, the pipe is not full, or there is gas in the pipe system, or air bubbles are inhaled. 2. The regular pulsating flow generated by the reciprocating pump in the piping system. 3. The liquid contains gas or bubbles. 4. There are strong magnetic fields such as motors around, and stray currents exist on the pipeline. 5. The electrode of the electromagnetic flowmeter is polluted, or the electrode suitable for the liquid to be measured is not properly selected. 6. The ground electrode of the electromagnetic flowmeter is not installed properly or is disturbed by the magnetic field. The above is the whole content of this article.
