Application of electromagnetic flowmeter in water treatment industry
The principle of measuring the electromagnetic flowmeter is Faraday's law of electromagnetic induction. The main components of the sensor are the measuring tube, electrode, excitation coil, iron core and yoke shell. The electromagnetic flowmeter is mainly used to measure the volume flow of the conductive liquid and the slurry in the closed pipe. It includes strong corrosive liquids such as acid, alkali, salt and so on. Electromagnetic flowmeter is widely used in the fields of petroleum, chemical, metallurgical, textile, food, pharmaceutical, paper and other industries, as well as environmental protection, municipal administration, water conservancy construction and so on. It
1. The measurement is not affected by the change of the fluid density, viscosity, temperature, pressure and electrical conductivity. 2, there is no obstruction in the measuring tube, no pressure loss, and the straight pipe is required lower;
3, a series of nominal paths from DN15 to DN3000. There are many options for sensor lining and electrode materials.
4. The converter uses a novel excitation mode, with low power consumption, zero stability and high accuracy. The range of the flow can reach 1500:1; 5, the transducer can form a body or separate type with the sensor.
6, the converter uses 16 bit high performance microprocessors, 2x16LCD shows that the parameter setting is convenient and the programming is reliable. The 7 and the flowmeter are bidirectional measuring system with three integrators: the total amount of forward, the total amount of reverse and the total difference; can display the Zhuang, reverse flow, and have a variety of output: electrical output
Flow, pulse, digital communication, HART;
8, the converter uses surface mount technology (SMT), with self checking and self diagnosis function.
