ITRON CENTRON® GPRS SMARTMETER
Functions and Features
Flexible Two-way DaTa ReTRieval anD ScheDuleD DaTa collecTion
Users can execute all appropriate TMS functionality using user configurable SmartMeter controlled schedules and TMS
controlled schedules and as well as on an on-demand basis.
auTomaTeD inTeRval DaTa/eneRgy uSage ReTRieval
The CENTRON GPRS SmartMeter module retrieves and transmits interval data for 1 unique energy value for intervals as small
as 5 minutes. Recorded events and exceptions with each interval are also transmitted to the TMS, which interprets them and
logs appropriate messages (e.g. time adjustments).
Real-Time inTeRval ReaDS
Real-time interval data acquisition enables utilities to implement Load Curtailment and Real Time Pricing (RTP) programs.
With this functionality, the user can configure the SmartMeter module to transmit load profile data as often as every 15
minutes at interval completion.
auTomaTeD RegiSTeR, SelF-ReaD anD Tou ReTRieval
The CENTRON GPRS SmartMeter module is configured by the TMS to read and transmit all or a subset of enabled registers
including totals, self-reads, maximum demand and time-of-use values.
DemanD ReSeTS
The CENTRON GPRS SmartMeter module executes Demand Resets using one of three methods: SmartModule initiated
schedules, TMS initiated schedules or TMS on-demand requests.
Real-Time meTeR evenT anD alaRm ReTRieval
The CENTRON GPRS SmartMeter provides automatic real-time alarm reporting of all events defined in the ANSI C12.19
standard
including history and event codes, ANSI Standard status and Manufacturer status alarms. Additionally, alarms received by
TMS can be automatically routed via e-mail to a specific user or group of users using the TMS Message Routing Interface.
Real-Time PoweR ouTage anD ReSToRaTion alaRmS
With built-in Ultra Capacitor energy storage, the CENTRON GPRS SmartMeter module will transmit a real time “last gasp”
notification when detecting an AC power outage without requiring the use of less reliable batteries. The CENTRON GPRS
SmartMeter also notifies the TMS when the AC power is restored and provides full configuration of these alarms based on
user defined durations.
SeRvice DiagnoSTic anD TamPeR DeTecTion aleRTS
The CENTRON GPRS SmartMeter can report power service and wiring errors detected by the meter including reverse polar-
ity, cross-phase and energy flow, phase voltage deviation, inactive phase current, phase angle displacement, and current
waveform distortion. In addition, the SmartMeter can detect and report exceptions for the following tamper events: number
of Demand Resets, Loss of AC power, and reported power outages.
The TMS configures a specific filter in the SmartMeter for each of these events enabling the transmission of a corresponding
alert only after the event is repeated a minimum of times within a specific duration. The TMS can also configure the
SmartMeter to reset the event counter when the alert message is transmitted.
