Introduction
LDE intelligent electromagnetic flow meter is my company uses the
most advanced technology research and development at home and
abroad all intelligent electromagnetic flow meter, its
wholly-Chinese high-speed magnetic converter core CPU. Very fast
calculation speed, high precision measurement and reliable
performance. Converter circuit design using international advanced
technology, up to ***5 ohms input impedance, common-mode rejection
ratio is better than **0dB, for the external interference and
*0Hz/*0Hz interference suppression is better than *0dB;
The conductivity can be measured at lower flow of the fluid medium.
Its use of non-uniform magnetic field sensor technology and a
special magnetic circuit structure, the magnetic field is stable
and reliable, but also reduced the size of a large, reducing
duplication and small-scale flow meter technology features. Allows
customers to "buy the rest assured that, with the worry, service
the Heart" is our purpose.
II. Operating Principle
Electric meter measuring principle is based on Faraday's law of
electromagnetic induction. Flow meter measuring tube is an
insulating material lining the non-magnetic alloy short pipe. Two
electrodes along the diameter direction of penetrating the wall
fixed to the measuring pipe. The electrode head and lining the
inner surface of the basic flush. Excitation coil wave pulse
excitation by both parties, it will be with the measuring tube axis
perpendicular to the direction to generate a magnetic flux density
B, magnetic field of work. At this point, if you have a certain
conductivity of the fluid flowing through the measuring tube.
Will be cut out of magnetic field lines induced electromotive force
E. Electromotive force E is proportional to the magnetic flux
density B, measurement of tube inner diameter d and the average
velocity v of the product. Electromotive force E (traffic signal)
detected by the electrodes and sent through the cable converter.
Converter will be traffic signal amplification processing, it can
display fluid flow, and can output pulse, analog current and other
signals for traffic control and regulation.
The electromagnetic flow meter has features of compact structure,
intuitive display, less power, wide turndown ratio. It is widely
used for oil petrochemical, metallurgy, machinery, brewage,
printing, food, environmental protection, and so on.
