Detailed Product Description

RF AMR SYSTEM WITH RF COMMUNICTION MODULE

The smart metering system allows energy suppliers to communicate directly with their consumers (AMI or AMR). Consumption information can be provided to domestic consumers through an integrated, in-home display (CDU). Among other potential benefits, they could offer electricity consumers accurate bills and provide information that could help them use less energy and encourage energy efficiency.  Combining smart metering technologies with e-payment platforms enables consumers to purchase electricity more conveniently from electricity retailers chosen by them. This will have households  enjoy the full benefits of competition in the electricity market.

FEATURES

1. Daily electricity bill
2. Choose to buy from power supplier with best offer
3. Time-Of-Use to save more money for customer
4. Extensive point-of-sales and methods of prepayment
5. Enhance anti-tampering functions

System Configuration:

Smart meter: Data and alarm can be uploaded to concentrator via built-in 
  RF module to achieve prepayment and AMI functions.

CDU: Show consumption and remain credit about electricity energy via   
   built-in RF module
Concentrator: Concentrator can not only capture the meter data and
   monitor the real time information via built-in RF module, but also can store 
   the data and sync the meter time. It supports the Ethernet or GPRS channel
   to transmit the data to main station with enhanced encryption techniques
   for billing, vending energy and monitoring any abnormal event.
Center station: Store and analyze meter data for managing electricity
  power supply and vending electricity
