LDG electromagnetic flowmeter manufacturers

LDG electromagnetic flowmeter manufacturers, many of my friends are new to this type of product, and they may not know this product very well. LDG is a representative of the model name of electromagnetic flowmeter. Let me first introduce the LDG electromagnetic flowmeter to you.　　 The measuring principle of LDG electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The measuring tube of the flowmeter is a short non-magnetic alloy tube lined with insulating material. Two electrodes are fixed on the measuring tube through the tube wall along the tube diameter direction. The electrode tip is basically flush with the inner surface of the lining. When the excitation coil is excited by the double-wave pulse, a working magnetic field with a magnetic flux density of B will be generated in the direction perpendicular to the axis of the measuring tube. At this time, if a fluid with a certain conductivity flows through the measuring tube. The electromotive force E is induced by the cutting magnetic field lines. The electromotive force E is proportional to the magnetic flux density B, and the product of the inner diameter d of the measuring tube and the average flow velocity v is measured. The electromotive force E (flow signal) is detected by the electrode and sent to the converter through the cable. After the converter amplifies the flow signal, it can display the fluid flow, and can output pulses, analog current and other signals for flow control and adjustment.　　 The above is mainly to introduce to you what is LDG electromagnetic flowmeter and the principle of LDG electromagnetic flowmeter. Let me introduce you to several internal components of LDG electromagnetic flowmeter.　　 Electrode: Its function is to draw out an induced electric potential signal proportional to the measured. Electrodes are generally made of non-magnetic stainless steel, and are required to be flush with the lining so that the passage of fluid is not obstructed. Its installation position should be in the vertical direction of the pipeline to prevent sediment from accumulating on it and affecting the measurement accuracy. When measuring some corrosive or some special media, the electrode needs to be replaced with more advanced materials, such as Hastelloy B, Hastelloy C, titanium electrode, tantalum electrode, etc., to deal with the measurement of different working conditions.　　 Lining: There is a complete electrical insulating lining on the inner side of the measuring pipe and the flange sealing surface. It directly contacts the liquid to be measured, and its function is to increase the corrosion resistance of the measuring tube and prevent the induced potential from being short-circuited by the wall of the metal measuring tube. The lining materials are mostly corrosion-resistant, high-temperature-resistant, and wear-resistant polytetrafluoroethylene plastics, ceramics, etc. Like the electrode, the lining is also divided into conventional neoprene lining and more suitable for the factory, such as polyurethane rubber, polyfluoroethylene propylene and other materials. The converter part is mainly a choice made by manufacturers of different levels, and will not affect the price of different models of the same flowmeter. In addition, we need to confirm some conventional industrial parameters, such as on-site caliber. Pressure, temperature, etc., of course, the most important thing is the confirmation of electrodes and linings. At present, there are many manufacturers of LDG electromagnetic flowmeters on the market, but there are also many middlemen. Kaidi is a manufacturer of LDG electromagnetic flowmeters.
