Abstract
A direction sensitive pulse initiator for a watthour meter having a rotating disc. A pair of sensors sense the presence of an indicator portion or portions, on the rotating disc or on an auxiliary disc, to produce electrical signals which are decoded to initiate clockwise rotation pulses and/or counterclockwise rotation pulses. The pulses are available to be recorded for compiling a record of metered power over a period of time. The sensor electrical signal outputs are decoded so as to determine if the previous exit direction of the indicating portion is the same as its present entry direction, and if this is true a rotation pulse of the appropriate direction is produced.
