ABSTRACT:
An energy meter composed of a meter chassis (2) having a transducer (4) connected to sense energy usage and to provide an output having a fixed relation to the sensed energy usage, a replaceable register (6) connectable to the transducer (4) for converting the output provided by the transducer (4) into a readable energy usage indication, a transducer identifying unit (18) secured to the chassis (2) and coded to identify the fixed relation between the transducer output and the sensed energy usage, and a transducer sensing unit (10) secured to the register (6) for coupling with the transducer identifying unit (18) when the register (6) is connected to the transducer (4).
