Installation and Operation

RF TWACS and Badger Meter, Inc. ORION

Transmitter

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 this data and transmits it to the EMTR.

Then it is retrieved by the utility, across power distribution lines.
