Intelligent Electromagnetic Flowmeter
Electromagnetic flowmeters can be used to measure the volume flow of conductive fluids in closed pipes. Widely used in flow measurement and control in industrial and agricultural production processes such as petroleum, chemical industry, iron and steel metallurgy, water supply and drainage, water conservancy irrigation, water treatment, environmental protection sewage measurement and control, papermaking, medicine, food, etc.
Product introduction


Product Composition

The electromagnetic flowmeter is composed of two parts: the electromagnetic flow converter and the electromagnetic flow sensor. The separate type also needs two dedicated double-layer shielded cables to connect the converter and the sensor.

Product type

The series of electromagnetic flow meters are divided into two structural forms: integrated type and separate type. It can be used in specified explosion-proof places.

The sensor is available in 7 different materials for the electrodes and 4 different materials for the lining.

flow meters

industrial flow meter


Electromagnetic flowmeter has the following characteristics:

Not affected by changes in fluid density, viscosity, temperature, pressure and electrical rate, the linear measurement principle can achieve high-precision measurement;

●There is no obstructed flow parts in the measuring pipe, the pressure loss is small, and the requirements for the straight pipe section are low;

●Nominal diameter DN6-DN2000 covers a wide range, and there are many options for lining and electrodes, which can meet the requirements of measuring various conductive fluids;

●The converter adopts programmable frequency low-frequency rectangular wave excitation, which improves the stability of flow measurement and reduces power loss;

The converter adopts 16-bit embedded microprocessor, full digital processing, fast operation speed, strong anti-interference ability, reliable measurement, high accuracy, and the flow measurement range can reach 1500:1;

●High-definition backlit LCD display, full Chinese character menu operation, easy to use, easy to operate, easy to learn and understand;

●With RS485 or RS232 digital communication signal output;

●It has the function of conductivity measurement, which can judge whether the sensor is empty or not, and has the function of self-test and self-diagnosis;

●Using SMD components and surface mount (SMT) technology, the circuit has high reliability;

●Can be used in corresponding explosion-proof occasions.

Working principle

Mathematical physical model

The working principle of the electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. When a conductor moves in a magnetic field, an induced electromotive force will be generated at both ends of the conductor perpendicular to the direction of the magnetic field and the direction of motion. The magnitude of the electromotive force is proportional to the velocity of the conductor and the magnetic induction of the magnetic field.
