DCSI introduces TWACS® two-way radio frequency link system for automatic meter reading

ST. LOUIS, Oct. 8, 2004 — Distribution Control Systems, Inc. (DCSI), a subsidiary of ESCO Technologies Inc. announces the release of their new Two-Way Automatic Communication System (TWACS®) Radio Frequency Link (RFL) technology, a consumption data transmission system between water, gas and/or propane meter encoders and a TWACS transceiver mounted in an electric meter. The TWACS RFL system fulfills the need for an alternative to hard-wired communications among proximate meters.

The TWACS RFL system provides “total consumption” data at any selectable or programmable time of day as well as “present consumption” based on hourly interval readings. Billing data is available for 23 hours or until the next data cycle time occurs. Hourly interval reading is over-written each hour, at which point the new billing data replaces the previous day’s information. This data is also available from the TWACS module at the time of an “on-request” read if needed. Water and/or gas consumption data is remotely relayed to the TWACS transponder that is mounted in the electric meter and transmitted to the utility from that collection point.

The TWACS RFL system has undergone thorough Beta testing, exposing the components to numerous adverse conditions, and has proven to be a sound technology that is applicable for meters on the same or neighboring home as the transceiver equipped electric meter. The development of this technology enables the TWACS system to provide automated metering solutions to gas, water, electric and the multi-utility marketplace without trenching or hard-wiring. In the future, Badger Meter’s ORION® Pit-Set water and gas metering solution is planned to interface with the TWACS RFL system, extending its capabilities to collect and transmit data from meters sited in the most challenging environments.
