Working principle

The measuring principle of electromagnetic flow meter is based on Faraday's law of electromagnetic induction. The sensor is mainly composed of a measuring tube with an insulating lining, a pair of electrodes installed by inserting the measuring tube wall, a pair of coils and an iron core to generate a working magnetic field. When a conductive fluid flows through the measuring tube of the sensor, a voltage signal proportional to the average flow rate of the fluid will be induced on the electrode. The signal is operationally amplified and processed to achieve various display functions.

Features

    • 01Measurements are not affected by fluid density, viscosity, temperature,pressure and conductivity.
    • 02No obstacles in the measuring tube, no pressure loss, low requirements for straight pipe section.
    • 03The LCD backlight type converter can be easily displayed and read in the sun or in a dark room.
    • 04In harsh environments, parameters can be set via infrared touch buttons without opening the cover of the converter (need to be customized).
    • 05Flow meter with bidirectional measurement system, built-in three totalizers: positive total, reverse total and total difference.
    • 06It has various forms of output: current 4-20mA, pulse, frequency, rs-485, HART.
    • 07The converter has self-diagnosis alarm output, no-load detection alarm output, flow upper and lower limit alarm, batch control (need to be customized) and other alarm output functions.
    • 08Not only for general processes, but also for the measurement of ore pulp, mud, coal slurry, paper pulp and paste liquid.
    • 09High-pressure electromagnetic flow sensor with PFA lining technology, resistant to high pressure and negative pressure, especially suitable for petroleum, chemical and other industries.
    • 10Explosion-proof instruments can be used in corresponding explosion-proof places.
