The measurement principle of electromagnetic flowmeter is based on Faradays law of electromagnetic induction.. The sensor part consists of a coil, electrodes, and insulation lining. During measurement, the excitation coil in the sensor is energized to generate a magnetic field. When the conductive fluid passes through the magnetic field, a small induced electromotive force is generated due to the cutting force of the magnetic field lines. The electrodes collect these small induced electromotive forces and transmit them to the converter part of the instrument for amplification, correction, and other operations. Then, they are converted into corresponding flow data through formulas, and finally displayed on the instrument or output to the upper computer system. When a conductive fluid flows through a magnetic field perpendicular to the flow direction, the co

nductive liquid induces an induced voltage E proportional to the average flow velocity. The induced voltage is detected by two electrodes in direct contact with the fluid, amplified, filtered, and shaped by a converter, and sent to the MCU for display and output control of instantaneous and cumulative flow rates. E=KBVD formula: E - Induced voltage K - Instrument constant B - Magnetic induction intensity V - Measurement of average flow velocity inside the pipe surface D - Flow meter diameter product structure diagram. A good electromagnetic flowmeter has high measurement accuracy and stable product performance. Before the electromagnetic flowmeter is bright, its accuracy is generally at 0.3 or 0.5 levels, while some small-diameter products can achieve 0.2 levels. Due to the particularity of its principle of measuring destructive width, it is necessary to measure the medium with a certain conductivity (generally greater than 5us/cm), and there are also certain requirements for measuring the starting flow velocity (generally greater than 0.5m/s). TSD electromagnetic flowmeter has many advantages in measuring fluid flow related to water affairs and is currently widely used in various industries.

(1) There are no obstructing flow components or pressure loss inside the measuring tube, and the requirements for the straight pipe section are relatively low;

(2) High measurement accuracy, strong stability, and strong resistance to vibration interference; (3) Measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity;

(4) With multiple electrode and lining options, it has strong resistance to medium corrosion.
