  1. Principle of operation of the HANSUNG electromagnetic water meter:
    • Electromagnetic water meter is a type of meter used to control the flow of wastewater, clean water, or other liquids … based on the principle of magnetic field when fluid passes through the sensors at both ends of the electrode produces an induced electrodynamic rate proportional to the velocity of the fluid flowing through the sensor, the obtained parameters are transmitted and displayed on the screen.
    • Because whenever fluid passes through the sensors, it generates electrodynamic rate, so it sends the results to the screen, so the meter can measure the water flow in both directions, we should pay attention when installing and operating.
  2. Advantages and Disadvantages of the HANSUNG electromagnetic water meter.
    1. Advantages.
      • By an smart, optimal design, the accuracy of the meter is increasingly improved.
      • Measurement results will be displayed on the electronic screen, making it easy to statistic the measurement results.
      • In the detached version, the dial can be placed in the control center cabinet, connected by signal cables.
      • Cast iron body construction (316 stainless steel option available) and PTFE liner for extended meter life.
    2. Disadvantage.
      • Since it is an electronic device, the meter needs a fixed power source for continuous operation.
      • In addition, the meter dial contains electronic devices, although with the IP68 waterproof and dust proof level, for extended life of the meter, we should not immerse the meter dial completely submerged in water.
      • In addition to the utility, the price of electromagnetic flow meter is often more expensive than other meters of the same size on the market.
  3. Some notes when using the HANSUNG electromagnetic water meter.
    1. In addition to the utility, the price of electromagnetic water meter is often more expensive than other meters of the same size on the market.
      • When pipes have lower than average fluid rates (excluding special cases, their own designs will be available). Another case is that the fluid velocity is too small, the results will be inaccurate, usually below 5%.
      • It contains gas, air in the ducts. Then, it changed the volume of the pipe and the fluid falsify the results.
      • Repeating the opening and closing of the fluid continuously for a short period of time as it increases the lag between the starting flow and the indicated velocity of the measuring device.
      • The flow meter will not work if the fluid used is magnetic or used to measure gas flow. In fact, when the velocity of the fluid with the mean conductivity is low, the meter does not work well. The reason is that due to the difference, the internal resistance of the sensor must be identical with the input resistance of the device.
      • Finally when fluiding by saline or seawater.
    2. Note when installing pipes.
      • Compared with other flow meters, the HANSUNG Electronic Water  Meter requires less straight pipe running, normally, the ratio when pre-installation is 7D and after-installation is 2D.
      • To limit swirl and reduce air overflow, it is recommended to install the meter vertically.
    3. Select the appropriate metering range.
      • According to the parameter 0.09 to 10m / s is the operating range of the meter as given by the manufacturer, but to ensure longevity and accuracy, let the device operate under the conditions of measuring average speed in the metering range at 60% of the maximum value.
