Estimating the term…
An electro-mechanical induction watt-hour meter has a rotatable disc and a projection on the base directed into the meter terminating in proximity of the rotatable disc. The projection is part of a pulse initiator system where a pulse signal is transmitted through a selected area of the base that is transparent to the signal. A signal is generated externally of the meter and chopped by rotation of the disc providing a pulse signal that passes through the base of the meter to a receptor external to the meter. The signal generator and the pulse signal receptor are both located in the enclosure defined by the base of the meter and the receptacle socket for the meter. The generated signal is disclosed as a light beam that, by way of light guides on the meter base, is directed to one side of the rotating disc and is directed by one light guide and to the other side of the disc where another light guide returns the chopped or pulsed signal to the receptor.
A device for use with an electro-mechanical induction watt-hour meter, said meter including a cover, a base and a disc mounted to rotate at a rate proportional to an amount of energy being consumed, said disc having a peripheral edge in proximity to the base, said device comprising:
An electro-mechanical induction watt-hour meter, comprising:
