Magnetic field influence indicators are used to fix the effects of constant magnetic fields on measuring devices ( water, ) which can influence the correct functioning of the counting mechanism. The use of magnets to stop meters is not a surprise to anyone, even if it is completely illegal. To protect the device from the influence of a constant magnetic field and to correct the fact of such impact, you can use a special indicator made in the form of an anti-magnetic sticker./p> The magnetic field influence indicator is a sealing sticker with a polymer container placed on it, in which magnetic elements made of rare earth material are located on a special base. The magnetic indicator works stably at air temperatures from -40ºС to +80ºС, resistant to solar radiation, relative air humidi
