    • Electromagnetic flow meterworks based on electromagnetic inducting phenomenon. When a conductor passes through a magnetic field, an inductive electric charge will be generated inside, so when there is flow passing through the magnetic field in the sensor, the two electrodes will generate an induced electromotive force and the induced electromotive force will be proportional to the flow rate through the sensor which will measure the flow rate indicators and the flow rate through the valve. Thereby the indicators will be displayed on the LCD display
    • In addition, for electromagnetic meters using turbine sensors, when water flows through and impact on the turbine, thereby turning the turbine, this number of turning will be calculated based on the sensor that counts the number of turning and converted to a flow measurement unit.

    • Some notes when installing and using Electromagnetic flow meter
      • Note that you should install the meter not submerged in water, to avoid water seeping into the board and causing damage or causing a fire.
      • When installing the meter, pay attention to the distance, the installation position to ensure a steady flow to help the meter accurately (refer to the catalogue for installation instructions)
      • The input of the power cord needs to be sealed with tape, the power cord must not be pulled above the display surface, this will cause water to enter through the power line to the board when installing meter outdoor.
      • It is necessary to tighten the bolts to ensure a solid connection, to avoid leakage of fluid flow
      • For the outdoor system, it is necessary to make an abat-vent for the meter to avoid the harmful effects of nature such as rain, sun, lightning …
      • Connect the earth wire directly to the ground to ensure the meter is free from magnetic contamination and give accurate measurement results
  3. Advantages and Disadvantages of Electromagnetic flow meter
    • Advantages
      • Electromagnetic flow meter has the outstanding advantage that the LCD display has two lines with 16 characters, in which line 1 continuously displays the volume of fluid passed through for one hour, line 2 shows the total amount of fluid passed through i.e. How much the amount of water discharged from the pipeline system is.
      • In terms of structure, the Electromagnetic flow meter is constructed of 316L stainless steel, and 321 carbon steel helps to resist corrosion caused by the environment, fluid flow from which the meter is highly durable.
      • Fluctuating water flow through the current meter produces analog signal currents corresponding to a signal level of 4 – 20mA, this signal source will be transmitted to the PLC cabinet processing center from which to control the related equipment
      • Diverse in operating voltage from 24VDC, 220VAC, 380VAC suitable for all current piping systems
      • Withstand high temperature and high pressure environment, and can be used outdoors, submerged in water for a short time due to the IP65, IP68 waterproof standards
    • Disadvantages
      • Perhaps the biggest disadvantage of this Electromagnetic flow meter is its high cost compared to conventional flow meters.
      • The meter has an LCD display design attached to the valve body, so the meter cannot be submerged underwater, as this will damage the meter.
