  1. In addition to the previous answers:

    1. Make sure to have a good ground with either grounding rings, or a grounding electrode.

    2. Most mag meters require about 3ft/sec flow rate to be accurate. You can increase the flow rate by downsizing on size to get the flow rate up. If downsizing, the the reducer must be concentric.

    3. The fluid measured must be electromagnetically conductive. For example water from a reverse osmosis system cannot be measured since deionized.

  2. Hi,

    1. Try to avoid electromagnetic noises coming from particles flowing through the water, high voltage equipments, low fluid conductivity.

    2. Install following the instructions manual given bu the manufacturer (horizontal/vertical positions, distance from pump, bends, etc) to ensure most accurate measurement.

    3. Install the flowmeter on the lowest point of the local pipe network to ensure full pipe condition. It is mandatory to have the pipe full with water.

    4. Avoid vibrations and install circuit surge protection.

    5. Make sure there is no flowing debris/materials that might damage the inner part of the electromagnetic flowmeter (it is recommended to install strainer upstream the meter).

  3. The following aspects should be noted when selecting the installation location:
    1. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields (large motors, large transformers, etc.) to prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor.
    2. It should be installed in a dry and ventilated place to avoid sun and rain. The ambient temperature should be -20 ~ +60 ° C, and the relative humidity is less than 85%.
    3. There should be plenty of space around the flowmeter for easy installation and maintenance.
