NYLD Intelligent Eletromagnetic Flowmeter


The NYLD intelligent type electromagnetic flowmeter consists of a sensor and a converter. It is based on Faraday's law of electromagnetic induction, which is used to measure the volume flow of conductive liquid with conductivity greater than 5μs/cm. It is an inductive meter for measuring the volume flow of conductive medium. In addition to measuring the volume flow of general conductive liquid, it can also be used to measure the volume flow of strong corrosive liquids such as strong acid and alkali and uniform liquid-solid two-phase suspension liquid such as slurry, pulp and paper pulp. It is wdely used for flow measurement of petroleum, chemical, metallurgy, textile, papermaking, environmental protection, food and other industrial sectors and municipal management, water conservancy construction, rivers and other fields.

NYLD Intelligent Eletromagnetic Flowmeter Operating Principle


According to the principle of Faradayelectromagnetic induction, a pair of detecting electrodes are mountedon the wall of the pipe perpendicular to the axis of the measuring pipe and the magnetic line of force.Whenthe conductive liquid moves along the axis of the measuring pipe, theconductive liquid cuts the magnetic line of force to generate an induced potential.The induced potential is detected by the two detection electrodes and the value is proportional to the flow rate.Thevalue is:

    E=KBVD Where: E- induced potential;
    K-thefactor related to the magnetic field distribution and the axial length;
    B-magnetic induction intensity;
    V-conductive liquid average flow rate;
    D-electrode spacing; (measure inner diameter of the pipe)

The sensor transmits the induced potential Eas a flow signal to the converter.After a series of digital processing such as amplification and conversion filtering, the instantaneous flow rate and the accumulated flow rate are displayed by the dot matrix liquid crystal with backlight.The converter has4-20mA output, alarm output and frequency output, and has RS-485 communication interface, and supports HARTand MODBUS

IP68 Intelligent Electromagnetic Flow Meter 0.1-10m/S 4-20mA 1


The electromagnetic flowmeter mainly consists of a sensor a nd a converter. The sensor includes a flange, a lining, an electrode, a measuring pipe, an excitation coil, a sensor housing and so on; the converter includes
1. Converter: provides a stable excitation current for the sensor, at the same time, converts the induced electromotive force obtained by the sensor into a standard electrical signal, and displays real-time flow and parameters for display, control and adjustment of the flow.
2. Lining: a complete layer of electrically insulating corrosion-resistant material on the inside of the measuring pipe and on the flange sealing surface.
3. Electrode: a pair of electrodes mounted on the wall of the measuring pipe to detect the flow signal, and another 1-2 grounding electrodes mounted for the grounding and anti-interference of the flow signal measurement.
