Working Principle

Explosion-proof magnetic flow meter working principle based on Faraday's law of electromagnetic induction, as shown in the figure. When a conductor in the magnetic field field movement, in the direction of the magnetic field, the direction of movement perpendicular to each other at the ends of the conductor, will produce an induced electromotive force (E), this induced potential by the two measuring electrodes detected by the numerical size of the size of the flow rate and the size of the magnetic field of the magnetic induction proportional to the size of the field, the value of the value of the: E = B.V.D.K

In the formula:

• K -- Coefficient related to the distribution of the magnetic field and the length of the axial direction
• B -- Magnetic induction
• V -- The average flow rate of conductive liquid
• D -- Electrode spacing (measuring tube inner diameter)

Application

Tips: Explosion-proof magnetic flow meter advantages

• Measurement is not affected by changes in fluid density, viscosity, temperature, pressure and electrical rate.
• Measuring tube without flow-obstructing parts, no pressure loss, straight pipe section requirements are low, the measurement of slurry has a unique adaptability.
• Nominal diameter DN15-DN150 covers a wide range, PETE lining and 316L electrode, can be applied to a variety of measurement media, with good corrosion and wear resistance.
• The converter adopts programmable frequency low-frequency rectangular wave excitation, which improves the stability of flow measurement with low power loss.
• High-definition backlit LCD display, Chinese and English menu operation optional, easy to use, simple operation, with RS485, 4-20mA, pulse 0-5V and other communication signal output (optional).
• With conductivity measurement function, can judge whether the sensor is empty pipe, with self-test and self-diagnosis function.
