  Telemeter \Te*lem"e*ter\, n. [Gr. ? far + -meter.]
     1. An instrument used for measuring the distance of an object
        from an observer; as, a telescope with a micrometer for
        measuring the apparent diameter of an object whose real
        dimensions are known.
        [1913 Webster]


  
     2. A measuring instrument which sends the information
        obtained from its sensors by radio to a distant station,
        usually to be recorded there; also, the complete system
        including measuring instrument, transmitter, and receiver.
        Such instruments are used, for example, to measure
        conditions in space or in other locations difficult of
        access for humans observers, or merely to allow one
        observer to monitor conditions in many places
        simultaneously.
