Meter reading methods and apparatus
 Meters having a plurality of rotating dials are read automatically by using radiant energy to sense the angular positions of the dials. A single radiant energy detector is time-shared among the several dials to reduce the cost of the meter reading apparatus. The meter can transmit meter readings and other information to remote locations. It can also receive, store, and act upon information received from remote locations. The meter can measure short-term demand, and can produce output signals for indicating and/or controlling demand.
