Intelligent electromagnetic flow meter/Automatic Flow Controller is a kind of high performance,high reliability of the flowmeter. Widely used in petroleum, chemical industry, food,electricity, steel, paper making, metallurgy, water supply and drainage,
petrochemical, medicine industry etc.
Measurement is independent of fluid density,viscosity ,humidity ,temperature , pressure and conductivity
There are no obstacle parts in the measuring tube,no pressure loss to the tube of which the straight part is of low requirement.
The sensor with advanced processing technology is of nice resistance to the negative pressure
The converter of the LCD backlight type shows and reading easily under the sun or in the dark room
In bad environment parameters can be set up through the infrared ray touch nubs without opening the cover of the converter.
The converter has alarm output function of self-diagnosis, empty load test,high and low limit of the flow, two-stage flow value, etc.
Not only apply in general process test,but also in the test of mineral serosity, paper pulp as well as pastry liquid,
High pressure type electromagnetic flow sensor adopting PFA lining technology which is resistant to high pressure and negative pressure is specially applicable in industries of oil, chemistry, etc
The method of measurement is based on Faraday's law of electromagnetic induction.When the conductive liquid moves within the magnetic field, voltage is induced in it, which is proportional to the velocity of theconductor. The equation is as below:
K: Coefficient of the flowmeter
B: Pulsed magnetic flux density
V: Average velocity of the media
D: Inner diameter of the Measuring pipe
When Measuring flow, fluid flow through the perpendicular to the direction of the flow field,the liquid flow conductivity induction out a and average flow velocity (volume flow) proportional to the voltage signal , the inductive voltage signal through the two and liquid direct contact with the electrodes of detection, and through the cable, and then sent to amplifier output current signal conversion unity.
