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