Wireless Telemetry System Replaces Leased Phone Lines at a Louisiana Water District and Reaps Quick Payback
2 PagesThe equipment was robust and working well but was expensive to operate. In addition, the phone line was vulnerable to severe weather, such as ice storms and hurricanes. Going Wireless With implementation of the wireless solution, SAWS leaders considered it prudent to keep as much of the existing system as possible, including the contact closures and float switches. One challenge was the high voltage signal passed along the telephone line to trigger the relays. 48VDC is quite different from the 0-5VDC typically used for sensors and relays. SAWS chose to keep the high-voltage capability because replacing it would add cost and complexity. Now, the signal to start and stop the well pumps is sent with a Ritron ® QuickTalk TM RQT, a 2-watt industrial-grade radio transmit
