General Description
The CENTRON meter is a solid-state, singlephase and network meter used for measuring
electrical energy consumption. The CENTRON incorporates a two-piece design combining
a base metrology with a variety of personality modules that snap on the standard meter base.
Utilizing the Hall Effect technology for accurate power measurement, the metrology portion
of the meter contains all measurement circuitry and calibration information, while the
personality modules contain the register functionality and communication mediums.
Each version of the meter is distinguished by the various personality modules that mount to
the standard meter metrology base. The personality modules available include the following
versions:

Energy only—C1S (LCD)

Demand—C1SD

Time-of-Use (TOU) with Demand—C1ST

Load Profile with TOU and Demand—C1SL

Energy only with radio frequency AMR—C1SR

Cellnet Fixed Network—C1SC

Energy plus demand with radio frequency AMR - C1SDR2/R3
