Abstract
A meter reading arrangement has an optical fiber transmission path made up of a pair of optical fibers connecting between a meter to be read and a meter interface unit. Light is transmitted over one of the fibers to an indicator on the meter and reflected light is transmitted by the second fiber to a transducer in the interface unit.
