Intelligent anti-corrosion electromagnetic flowmeter

采用世界最新技术,利用恒流低频三值矩形波或双频矩形波励磁,既有矩形波磁场的优点,又克服了正弦波 DEC-LD series intelligent anti-corrosion electromagnetic flowmeter uses the latest technology in the world. It uses constant current low frequency three-value rectangular wave or double-frequency rectangular wave excitation. It has the advantages of rectangular wave magnetic field and overcomes the sine wave.


The shortcomings of the magnetic field; it can also eliminate errors caused by power supply voltage fluctuations, power supply frequency changes and excitation coil impedance changes; and it has excellent zero point stability and is not affected by fluid noise interference


. So it has the characteristics of high stability and high reliability. The measuring principle of the intelligent anti-corrosion electromagnetic flowmeter is based on Faraday's law of electromagnetic induction.


The sensor is installed on the measuring pipeline. The converter can be combined with the sensor and is called an integrated electromagnetic flowmeter. The converter is installed within 30 meters or 100 meters from the sensor.


In the case of inside, the two are connected by a shielded cable, which is called a separate electromagnetic flowmeter. The main components of the intelligent anti-corrosion electromagnetic flowmeter sensor are: measuring tube, electrode, excitation coil, iron core

With yoke housing. Intelligent anti-corrosion electromagnetic flowmeter is mainly used to measure the volume flow of conductive liquid and slurry in closed pipelines. Such as water, sewage, mud, pulp, various acids, alkalis, salts


Solution, food slurry, etc. Intelligent anti-corrosion electromagnetic flowmeters are widely used in petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking and other industries, as well as environmental protection, municipal management, and water conservancy construction.


And other fields.

产品特点: Product features of intelligent anti-corrosion electromagnetic flowmeter :


1.The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity;

2. There are no obstructing flow parts in the measuring tube, no pressure loss, and low requirements for straight pipe sections;


3. The nominal diameter of the series is DN15 ~ DN3000. Multiple choices for sensor liner and electrode materials;


4. The converter uses a novel excitation method, low power consumption, stable zero point and high accuracy. Flow range can reach 1500: 1;

5. The converter can be integrated or separated with the sensor;


6. The converter uses a 16-bit high-performance microprocessor, 2x16 LCD display, convenient parameter setting and reliable programming;

7. The flow meter is a two-way measurement system with three totalizers: forward total, reverse total and difference total; it can be displayed. Zhuang, anti-flow, and has multiple outputs: current, pulse, digital communication, HART;


8. The converter uses surface-mount technology SMT, with self-checking and self-diagnostic functions

采用世界最新技术。 Intelligent anti-corrosion electromagnetic flowmeter uses the latest technology in the world. The use of constant-current low-frequency three-value rectangular wave or double-frequency rectangular wave excitation has both the advantages of the rectangular wave magnetic field and the disadvantages of the sine wave magnetic field; it can also eliminate

The error caused by power supply voltage fluctuations, power supply frequency changes, and excitation coil impedance changes; and has excellent zero point stability and is not affected by fluid noise interference. So it has the characteristics of high stability and high reliability. Measurement principle

It is based on Faraday's law of electromagnetic induction. The intelligent anti-corrosive electromagnetic flowmeter consists of a sensor and a converter. The sensor is installed on the measuring pipeline. The converter can be combined with the sensor and called an integrated electromagnetic flowmeter.

The converter is installed within 30 meters or 100 meters from the sensor, and the two are connected by a shielded cable called a separate electromagnetic flowmeter. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke

case. It is mainly used to measure the volume flow in conductive liquids and slurries in closed pipes. Such as water, sewage, mud, pulp, various acids, alkalis, salt solutions, food slurry, etc., widely used in petroleum, chemical, metallurgy, textile

Weaving, food, pharmaceutical, papermaking and other industries, as well as environmental protection, municipal management, water conservancy construction and other fields.
