ABSTRACT:
A cyclometer register in an electric watthour meter includes a free counterweight for producing a kinetic-energy kick for advancing superior cyclometer drums. A drum counterweight, affixed to the units cyclometer drum, is disposed 180 angular degrees out of phase with the free counterweight. The drum counterweight has a moment equal to one-half the moment of the free counterweight, whereby the maximum sum of moments and the peak-to-peak moment is reduced by half. A harmonic counterweight rotates at twice the angular rate of the units cyclometer drum and reflects one-quarter of the moment of the free counterweight back to the driving elements. The harmonic counterweight reduces further the maximum moment as seen by the driving elements and also increases the minimum moment so that the variability in moment is reduced, thereby enabling an offsetting constant increase in meter torque and reducing metering error.
