<p>13 The present invention is for an induction meter having a voltage and a current magnetic sections each producing magnetic flux for rotating an electroconductive disk at a rate responsive to the magnetic flux. The voltage magnetic section is comprised of a substantially E-shaped laminated magnetic core having a center leg terminating at a main pole face and two adjacent legs terminating at coplanar auxiliary pole faces on opposite sides of the main pole face. The first and last laminae of the core define a first and a second side, respectively, of the core. A voltage coil is wound about the center leg. A fixed light load adjuster bracket is located in magnetic proximity to the first side of the core. The bracket has a fixed tab extending over a portion of one of the auxiliary pole faces. A nonmagnetic spacer is located between the first side of the core and the light load adjuster bracket. The spacer, the light load adjuster bracket and the laminae of the core are fastened together so as to provide a rigid assembly. The light load adjuster bracket carries a movable tab extending over adjustable portions of the other auxiliary pole face and the main pole face thereby providing an adjustable magnetic flux shunt path. The light load adjuster bracket toether with both the fixed tab and the movable tab act as an additional magnetic flux shunt path.</p> |
