Magnetic field coupler for fluid meter

摘要

A magnetic field coupler has a plurality of magnetic poles with respective first ends located immediately adjacent a circular path of a rotating magnet in a meter. The magnetic poles have respective opposite ends located immediately adjacent a magnetic sensor in a meter reading device. A nonmagnetic material separates each of the plurality of poles from all others of the plurality of the poles, and the nonmagnetic material is joined with the poles to form a unitary structure.
