MAGYN Intelligence Electromagnetic Flow Meter
MAGYN Intelligence Electromagnetic Flow Meter
MAGYN Serials Intelligence Electromagnetic Flow Meter conducts measurement based on the principle of the Faraday Electromagnetic Induction Law. When conductive liquid flows in a magnetic field and incises the magnetic flux, there generated induced electromotive force E in the conductor, as below.


k--------Instrument constant
B--------Magnetic induction density
V--------Average velocity in the cross section of a measured pipe
D--------Inner diameter of a measured pipe

When measuring a flow rate, the conductive liquid flows at a velocity of V perpendicularly through a magnetic field, which inducts a voltage that is direct proportional to the average velocity. The inducted voltage signal is measured on two or more poles immediately contacted with the liquid, sent to a convertor through a cable, and then intelligentized before it is transferred to and displayed in a LCD or converted into a 4¡«20mA or 0¡«1kHz output. Patent No.: ZL 03 2 63802.7

Feature and Usage

Absolute When the temperature, pressure, viscosity and density of the measured fluid changing, the flow meter do not be influence.
Easy Maintenance No moving parts in measuring tube, so easy maintenance.
Widely Use Can measure conductivity liquid, fiber content conductivity liquid, solid content conductivity liquid, suspending material conductivity liquid whenever fiber or solid.
Easy Install Install any angle only need liquid full of the pipe. Straight pipe require 5D for upper stream and 2D for down stream
Large Turndown Ratio The turndown ratio can reach to 1:100
Enclosure For DN15~DN1200 is IP68
High Intelligence Back light English/Chinese LCD display, Meun setting control, three grades password protection, Two-way measuring available, slight signal removal, Auto flow compensate and other function.
SMT Technical Intelligence self-detect and self-diagnoses, many kinds of alarming
SMART Excitation Low power consumer, zero stability, longtime reliability
Multi- Output 4-20mA or 0~10mA current output, Standard Pulse Output, RS485 computer communication output
Slect the right lining and electrode material can measure nearly all conductive liquid.
The power supply system has good voltage vibration adaptability. The power system also resist well electromagnetic interfere.
