Chapter 2 • Functional Description

®

The DCSI RF TWACS System and the Badger Meter, Inc. ORION

®

 transmitter 

are capable of data communication. The ORION

®

 module uses the RF bubble-up 

broadcast mode to communicate (one way) from the auxiliary meter to the electric 
meter. The ORION

®

 transmitter sends customer usage data (at 100Kbps) every 

five seconds on the 916.450 MHz frequency channel. The RF TWACS system 

receives and processes this data via the EMTR-3 where it relays on request to the 

UMT module. Then it can be retrieved by the utility across power distribution 

lines.
