Measuring principle: The measuring principle is based on Faraday's law of electromagnetic induction. That is: when a conductive fluid moves in a magnetic field by cutting the magnetic lines of force, an induced electromotive force is generated in the conductor. To measure the flow, the fluid flows through a magnetic field perpendicular to the flow direction. The flow of conductive liquid induces a voltage signal proportional to the average flow rate (i.e. volume flow rate). The induced voltage signal is detected by two electrodes that are in direct contact with the liquid and transmitted via a cable line to an amplifier, which then converts it into a unity current output signal.

Excitation mode: At present, the electromagnetic flowmeter at home and abroad has a variety of different excitation modes, such as low-frequency square wave excitation mode, pulse DC excitation mode, as well as dual-frequency excitation, frequency-adjustable rectangular wave excitation, pulse AC excitation and so on. 

Introduction：Supmea RZ-LD split-type/integrated electromagnetic flowmeter is a flowmeter consisting of a sensor and a converter, which is used to measure the volume flow rate of all kinds of conductive liquids in the pipeline. It adopts low-frequency square wave excitation method, with small power consumption and stable zero point. The use of CMOS digital circuits and integrated arithmetic circuits with high reliability. Measurement accuracy is not affected by changes in fluid density, viscosity, pressure river conductivity. Measuring range corresponds to the flow rate range: 0-1m/s to 0-10m/s, power consumption: less than 15VA.

Other types of intelligent electromagnetic flowmeter can be divided into two categories: phenomenon line display type (one-piece) and remote display type (split). With letters / digital display function, key or infrared remote control operation, zero self-adjustment function, conductivity automatic migration function, self-checking fault alarm function, upper and lower limits of the flow rate alarm function, power outage protection function, removable, scraper and fixed electrode structure, vibration-resistant performance, equipped with RS-232C/RS-485 communication, control signals, good corrosion resistance, no moving parts, long service life. Its main technical parameters are as follows: pipe caliber of 10-300mm, flow rate range 0.3-11m/s.

Produced ADMAGSE electromagnetic flowmeter, its overall structure is more compact and cheaper, but its high accuracy, easy to use and maintain, ADMAGSE housing is divided into two chambers, which separates the electrical part from the surrounding, so that it is easy to be wired. And it can be with BRAIN or HART communication. Using pulse DC excitation, the main technical indicators: through the range from 15mm to 200mm, the flow rate range is 0-10m/s, the measurement accuracy of ± 5%, power consumption of 10W. development and production of the LF140/LF240 electromagnetic flowmeter consists of a detector and converter with HART communication, with LCD display flow rate and total flow and other parameters, the main technical indicators. and total flow and other parameters, the main technical indicators are as follows: measurement accuracy of ± 0.5% or ± 0.25%, the flow rate measurement range of 0-0.5m / s to 0-10m / s, the caliber range of 25-100mm. the main technical indicators: domestic and foreign advanced electromagnetic flowmeter have a flow rate, flow rate and other parameters of the display function, and has a communication function with the computer and other equipment.
