INDICATOR OF MAGNETIC ACTION ON ENERGY, GAS, WATER OR HEAT ACCOUNTING METERS

摘要

An indicator of magnetic action on energy, gas, water or heat accounting meters at least one element of which is made of hard-magnetic materials intended for fixation of magnetic action by remanent magnetic induction and/or other magnetic field parameters of this element. For visual indication of magnetic action it comprises at least one ferromagnetic element having a property to change its initial location relative to the ferromagnetic element made of the hard-magnetic material at external magnetic action.
