Electromagnetic flowmeters are widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal management, water conservancy construction and other fields.
The principle of electromagnetic flowmeter measurement is Faraday's law of electromagnetic induction. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke housing. Electromagnetic flowmeters are primarily used to measure the volumetric flow in conductive liquids and slurries in closed conduits. It includes highly corrosive liquids such as acids, bases, and salts.
Features:
1. Measurements are not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity;
2. There is no obstructive flow component in the measuring tube, no pressure loss, and the requirements of the straight pipe section are low;
3, series nominal diameter DN15 ~ DN3000. Sensor lining and electrode materials are available in a variety of options;
4. The converter adopts novel excitation mode with low power consumption, stable zero point and high precision. Flow range up to 1500:1
5. The converter can be integrated with the sensor or separated;
6. The converter adopts 16-bit high-performance microprocessor, 2x16LCD display, convenient parameter setting and reliable programming;
7. The electromagnetic flowmeter is a two-way measuring system with three totalizers: positive total, reverse total and total difference; can be displayed. Zhuang, anti-flow, and has a variety of outputs: current, pulse, digital communication, HART;
8, the converter uses surface mount technology (SMT), with self-test and self-diagnosis function; this article is transferred from http://
