Stainless steel intelligent electromagnetic flowmeter

I believe many small partners in the automation industry have heard of the stainless steel intelligent electromagnetic flowmeter. The stainless steel intelligent electromagnetic flowmeter also plays a very important role in the automation industry. Some important industries, such as petroleum, metallurgy, printing and dyeing, medicine, water treatment and many other industrial sites can see it, but there are very few people who can really understand the stainless steel intelligent electromagnetic flowmeter. The following editor has compiled some knowledge about the stainless steel intelligent electromagnetic flowmeter, hoping to help you understand the stainless steel intelligent electromagnetic flowmeter more deeply. We all know that the working principle of the electromagnetic flowmeter is based on the principle of flange electromagnetic induction. A pair of detection electrodes are installed on the pipe wall perpendicular to the axis of the measuring tube and the magnetic field line. When the conductive liquid moves along the axis of the measuring tube, the conductive liquid Cutting the magnetic field lines generates an induced electric potential, which is detected by two detection electrodes, and the value is proportional to the flow rate. The sensor uses the induced electromotive force as a flow signal and transmits it to the converter. After signal processing such as amplification, conversion and filtering, the instantaneous flow and accumulated flow are displayed by a dot matrix liquid crystal with backlight.　　The measurement accuracy of the stainless steel intelligent electromagnetic flowmeter is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity. The sensor induced voltage signal has a linear relationship with the average flow rate, so the measurement accuracy is high. The stainless steel intelligent electromagnetic flowmeter has no obstructions in the measuring pipeline, so there is no additional pressure loss; there are no moving parts in the measuring pipeline, so the sensor has an extremely long life. The stainless steel intelligent electromagnetic flowmeter, because the induced voltage signal is formed in the entire magnetic field-filled space, is the average value of the pipeline carrying surface, so the straight pipe section required by the sensor is shorter, and the length is 5 times the pipe diameter. The sensor part of the stainless steel electromagnetic flowmeter only has the inner lining and electrode in contact with the liquid to be measured. As long as the electrode and inner lining material are selected reasonably, it can resist corrosion and wear.　　So how do we choose the electromagnetic flowmeter correctly? 　　What kind of stainless steel intelligent electromagnetic flowmeter should be selected according to the physical and chemical properties of the fluid medium to be measured. According to the working principle of the electromagnetic flowmeter, the fluid that can be used to measure the flow of the electromagnetic flowmeter must be conductive. Strictly speaking, except for high-temperature fluids, any fluid with a conductivity greater than 20us/cm can be selected for the corresponding electromagnetic flow. A meter is used to measure the flow, because non-conductive gas, steam, oil, acetone and other substances cannot be used to measure the flow with an electromagnetic flowmeter. As for the diameter of the sensor, the flow rate of the flow meter is preferably within the range of 0.1-5m/s. At this time, the diameter of the flowmeter can be selected to be the same as the user's pipe diameter.　　Stainless steel intelligent electromagnetic flowmeter, the stainless steel generally refers to the casing of the electromagnetic flowmeter. The electromagnetic flowmeter made of stainless steel is resistant to weak corrosive media such as air, steam, and water, and has a longer service life. The lining material of the stainless steel intelligent electromagnetic flowmeter is mainly rubber lining and PTFE lining. The rubber lining is mainly suitable for wear-resistant media, the rubber lining is mainly neoprene and polyurethane rubber, and polyurethane rubber is suitable for strong abrasion media. , Tetrafluoroethylene lining is mainly suitable for corrosion-resistant media. Tetrafluoroethylene substrate is mainly polytetrafluoroethylene and polyperfluoroethylene propylene. Polytetrafluoroethylene propylene is suitable for strong abrasive media. Electrode materials are mainly divided into stainless steel containing molybdenum, Hastelloy B, Hastelloy C, titanium tantalum, stainless steel carbide Wu.　　Different materials are suitable for different industrial occasions, and the corresponding prices will be different.
