Magneto’s magnetic field indicators are designed for the permanent registration of a magnetic field presence. They can be used for the identification of tamper with water meters, watt-hour meters and gas meters with the use of an external magnetic field. The one-threshold magnetic field indicators MFI-3 register a strong magnetic field coming from neodymium magnets. The two-threshold indicators MFI-4 register a magnetic field coming from ferrite magnets (the first threshold) and from neodymium magnets (the second threshold). Both indicators are manufactured in two versions: to install on the internal surface of transparent casing or on the external casing surface of a measuring device. The passive indicators do not require any energy supply and do not have any movable elements.
