METHOD FOR THE IDENTIFICATION OF THE FACT OF EXPOSURE OF A POWERFUL NON-MODE MAGNET TO THE COUNTER OF THE MUNICIPAL RESOURCE

摘要

FIELD: physics.;SUBSTANCE: method for detecting the fact effects the powerful neodymium magnet counter public resource, consists in the fact that in the design of the counter at locations most sensitive to the magnetic field action, either around the inner perimeter mounted one or more inductor particular shape so that plane coil is parallel to the body of the counter with a minimum distance therebetween, whereas the magnetic flux in the inductor is changed, EMF induction and induction current are generated, which are fixed at the smart meter in the nonvolatile memory with the output to the liquid crystal indicator in the form of a dumb counter actuated indicator light.;EFFECT: increasing the accuracy of detecting the impact of a utility resource on the meter.;2 dwg
