Description

Non-magnetic and non-valve control Internet of things water meter

Technical Field

The utility model belongs to the technical field of the networking water gauge, in particular to no magnetism does not have valve accuse thing networking water gauge.

Background

The non-magnetic sensing in the water meter measurement is defined relative to the magnet sampling, and is a convention. Specifically, magnetic sampling means that a small magnet is arranged on a rotating pointer of an indicating disc in the mechanical water meter, and the sampling is realized by a reed switch or a Hall element outside.

The non-magnetic state means that the rotating pointer does not have the small magnet, a metal sheet which is not influenced by magnetism is used for replacing the magnet, and the technology for collecting the rotating rotation and direction of the metal sheet is called non-magnetic sampling.
