Application of Electromagnetic Flow Meter in Acetic Acid Production

Abstract: The application information of electromagnetic flow meter in acetic acid production is provided by excellent flow meter and flow meter manufacturers. In the process of producing acetic acid, it has properties of corrosiveness. Many kinds of media are corrosive in high temperature and corrosive environment. Most of the acetic acid, the measuring device is placed in the process to meet the conventional measurement value, and the electromagnetic flowmeter needs to be used. , to replace. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the application of electromagnetic flowmeters in acetic acid production. In the process of producing acetic acid, it has properties of corrosiveness. Many kinds of media are corrosive in high temperature and corrosive environment. Most of the acetic acid, the measuring device is placed in the process to meet the conventional measurement value, and the electromagnetic flowmeter needs to be used. , to replace the flowmeter of the electromagnetic flowmeter, some regular maintenance and forward failure analysis. Orifice plates used in acetic acid devices, vortex, turbine, and oval gear flowmeters. Many of these shortcomings flow meters: easy to wear, resistant to leakage of corrosive media, short life, heavy maintenance, it will be difficult to meet the production requirements [1]. Instead, move the equipment and design a new type of flowmeter with a technical transformation of the electromagnetic flowmeter. Although there is no substandard acetic acid production process, this change can greatly reduce the investment and reduce the intensity of maintenance. In actual production, we have achieved very satisfactory results. It can be a variety of classification methods, the classification of the composition, the classification of the sensors connected to the pipeline, the classification of the sensors, the classification of the size of the electromagnetic flowmeter, the classification of the electromagnetic flowmeter, in this article, the stimulus I will introduce the classification of Way. Excited DC-. A small number of electromagnetic flow meters, such as those used to measure the heat flow of liquid mercury and liquid metals such as sodium and potassium at room temperature only. Pumping power frequency exchange. It is not the cause of the excitation power supply that electromagnetic interference is easily affected by the high frequency electromagnetic flowmeter 50 Hz, zero drift, and gradually becomes a rectangular excitation frequency with low frequency. However, in the measurement of the solid-liquid two-phase flow slurry and, because of the low frequency of the square wave excitation, a sharp noise occurs on the surface of the electrode, and the AC meter at the excitation frequency is able to overcome this disadvantage without the use of an AC power source. , some electromagnetic flowmeters, both at home and abroad. Low frequency rectangular wave excitation type. The stability of the zero point, and the low frequency square wave excitation mode of the energy consumption is the main excitation mode of the electromagnetic flowmeter. Three binary zeros of the waveform - negative-zero-negative and positive binary-positive. The excitation frequency of the electromagnetic flowmeter is set by the user, it is generally a small diameter instrument with high frequency and a low frequency with a large diameter instrument. Type two-way excitation. Mainly to improve the stability and response characteristics of the device, the waveform of the excitation current is superimposed on the high frequency of the square wave and the low frequency of the square wave, to overcome both the value and the current noise of the slurry noise excited by the square wave. The electromagnetic flowmeter is a pipeline flow measuring instrument based on Faraday's law of electromagnetic induction to measure the volume flow of conductive liquids. Since the member of the electromagnetic flowmeter, it does not and cannot rotate as part of the pressure loss that nearly prevents the fluid flow of the member. Due to the reasonable selection of electrodes and pipelines of electromagnetic flowmeters for liquid contact measurement only as long as they have electrodes, and lining materials that have excellent corrosion resistance and wear resistance [2], they can be easily installed horizontally and vertically On the slope, it is possible to install. You can usually achieve a measurement accuracy of 0.5%; 20:01 from a large range. The electromagnetic flowmeter that can be in the operation process is not allowed, because the failure caused by various measurement phenomena occurs, it is generally divided into two categories: the operation of the electromagnetic flowmeter fails. Failure of the flowmeter itself, failure caused by damage to components caused by failure, due to changes in external conditions, for example, unreasonable installation, distorted flow through deposits and fouling. Status and Prospects of Platinum-Iridium Electrodes in the Field of Flow Meters There are two ways to generate a bubbling liquid from an external gas aspirated gas or convert a dissolved gas into a free-form bubble in the medium. Since the output signal is different from the electrodes, the electrodes pass through the air bubbles, so that the open flow signal input circuit is instantaneously covered when the medium is in the presence of large air bubbles. Being able to do this to determine the cause of this fluctuation, the loop current of the magnetic field is interrupted, the air bubbles change, and if you cut off the flowmeter it also shows, so that the electromagnetic flowmeter that proves the fluctuations I will. The resistance value of the electrode loop resistance of the electromagnetic flowmeter is higher than that of the normal electromagnetic flowmeter, and the electrode resistance of the electromagnetic flowmeter is measured with a multimeter. The electromagnetic flowmeter is installed at the location of the air due to the external point, or the high ductwork caused by the electromagnetic flowmeter,The change in the inlet flow rate of the input medium is measured and the stored gas you point to the installation position in the pipeline to install or set the change of the lowest electromagnetic flowmeter of the U-shaped pipe, it is necessary to replace. However, in order to set up the air bag it is not easy to modify to address this situation, in some cases the exhaust gas is installed upstream of the flow meter due to the mounting position or diameter of the electromagnetic flow meter.
