    • Corrosion protection, abrasion resistant;
    • High accuracy, Stable performance;
    • High level of anti-vibration and anti-jamming, wide measuring dimensions.
    • Multi-Output Interface4~20mA, Pulse, Alarm Outputs, RS-485 and Modbus Communication.

    2. Structure and Operation Principle

    2.1. Structure

    KFL-DC series electromagnetic flowmeters are made up of sensor and transducer, together with LCD screen, current and pulse output, alarm signal and RS-485 communication.



    2.2 Operating Principle


    Faradays Laws of Induction form the basis for the electromagnetic flowmeters. It states that a voltage is induced in a conductor as it moves through a magnetic field.

    This principle is applied to a conductive fluid which flows through a magnetic field generated perpendicular to the flow direction (see Schematic).

    The voltage induced in the fluid is measured at two electrodes, installed diametrically opposed. This signal voltage UE is proportional to the magnetic induction B, the electrode spacing D and the average flow velocity v. Noting that the magnetic induction B and the electrode spacing D are constants, a proportionality exists between the signal voltage UE and the average flow velocity v. The equation for the volume flow shows that the signal voltage UE is linear and proportional to the volume flowrate. The induced signal voltage is processed in the converter into scaled, analog and digital signals.
