EMFM electromagnetic flowmeterIt consists of two parts: a sensor that directly contacts the pipeline medium and an upper signal converter. It works based on Faraday's law of electromagnetic induction and is used to measure the flow rate of conductive liquids with a conductivity greater than 3 μ s/cm. It is an instrument for measuring the flow rate of conductive media. In addition to measuring the flow rate of general conductive liquids, it can also be used to measure highly corrosive liquids such as strong acids and alkalis, as well as liquids with uniformly suspended liquid-solid phases, such as mud, slurry, pulp, etc.

The electromagnetic flowmeter can not only meet on-site display requirements, but also output 4-20mA current signals for recording, adjustment, and control. It has been widely used in industrial technology and management departments such as chemical, environmental protection, metallurgy, medicine, papermaking, and water supply and drainage. An electromagnetic flowmeter that uses the principle of electromagnetic induction to measure the flow velocity of a medium fluid. It adds a magnetic field on both sides of the pipeline, and when the measured medium flows through the pipeline, it cuts the magnetic field lines, generating an induced potential on the two detection electrodes, which is proportional to the velocity of the fluid. It can be used to measure the flow rates of various suspended solids, gasification vapors, and viscous substances such as acid, alkali, salt solutions, coal water slurry, slurry, mortar, pulp, resin, rubber emulsion, synthetic fiber slurry, and photosensitive latex. Electromagnetic flow meters have good sealing performance and can also be used in tap water and groundwater systems. Moreover, the measurement process does not come into contact with fluids, making it suitable for the pharmaceutical, biochemical, and food industries.

Therefore, we pay great attention to every aspect of the design process, including product structure, material selection, process formulation, production assembly, and factory testing. We have also independently designed a set of advanced production equipment and flow calibration devices for electromagnetic flow meters in China, which can effectively ensure long-term high-quality products in both software and hardware. The electromagnetic flowmeter is specially designed with a backlight wide temperature range English LCD display, with complete and practical functions, intuitive display, and convenient operation and use.

EMFM electromagnetic flowmeterWorking principle: It is based on Faraday's law of electromagnetic induction. In an electromagnetic flowmeter, the conductive medium inside the measuring tube is equivalent to a conductive metal rod in Faraday's test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows through, an induced voltage is generated. The induced voltage generated by measuring the two electrodes inside the pipeline. The measuring pipeline achieves electromagnetic isolation from the fluid and measuring electrodes through non-conductive lining (rubber, PTFE, PTFE, etc.).
　　

Corrosion resistant chemical EMFM electromagnetic flowmeterThe measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity. The sensor's induced voltage signal is linearly related to the average flow rate, resulting in high measurement accuracy. There is no obstruction in the measuring pipeline, so there is no additional pressure loss; There are no movable parts inside the measuring pipeline, so the sensor has an extremely long lifespan. Due to the fact that the induced voltage signal is formed in the entire space filled with a magnetic field and is the average value on the surface of the pipeline, the sensor requires a shorter straight pipe section, with a length of 5 times the diameter of the pipeline The sensor part only has the inner lining and electrodes in contact with the measured liquid. As long as the electrode and inner lining materials are selected reasonably, they can be corrosion-resistant and wear-resistant. The converter adopts microcontroller (MCU) and surface mount technology (SMT), which have reliable performance, high accuracy, low power consumption, stable zero point, and convenient parameter setting. Click on the Chinese and English display LCD to show cumulative flow, instantaneous flow, flow rate, flow percentage, etc. A bidirectional measurement system that can measure both forward and reverse flow rates. Using special production processes and high-quality materials to ensure the stability of product performance over a long period of time.

The EMFM split type electromagnetic flowmeter is an induction instrument that measures the volume flow rate of conductive medium inside a tube based on Faraday's law of electromagnetic induction. It uses embedded microcontroller technology to achieve digital excitation, and adopts CAN fieldbus on the electromagnetic flowmeter, which has reached the domestic level of technology. The split type electromagnetic flowmeter can not only meet on-site display requirements, but also output 4-20mA current signals for recording, regulation, and control. It has been widely used in industrial technology and management departments such as chemical, environmental protection, metallurgy, medicine, papermaking, and water supply and drainage. In addition to measuring the flow rate of general conductive liquids, the split type electromagnetic flowmeter can also measure the volumetric flow rate of liquid-solid two-phase flow, high viscosity liquid flow, and salt, strong acid, and strong alkali liquids. The instrument structure is simple, reliable, without moving parts, and has a long working life. No flow blocking components, no pressure loss or fluid blockage. The measurement accuracy is not affected by the type of measured medium and its physical parameters such as temperature, viscosity, density, pressure, etc. Different combinations of PTFE or rubber lining materials and electrode materials such as Hc, Hb, 316L, Ti can adapt to the needs of different media.

EMFMInstallation requirements for electromagnetic flowmeter: It should be kept away from strong magnetic field equipment. Avoid places with strong vibrations and corrosiveness. Pipelines that do not allow flow interruption in the process should be equipped with shut-off valves and bypass pipelines when installing flow meters. There should also be a certain straight pipe section upstream of the flowmeter sensor, usually between 5D and 10D. It can be installed horizontally, vertically, and diagonally, but it is necessary to ensure that the measuring tube is coaxial with the process pipeline and that the measuring tube is always filled with liquid. The measuring tube, housing, shielded wires of the leads, and the pipelines at both ends of the sensor must be reliably grounded and must not be shared with the grounding of other electrical equipment. This is a special installation requirement for electromagnetic flow meters.
