St Johns County, FL, U.S.A. — (METERING.COM) — July 31, 2007 – The existing water meters in parts of St Johns County are being replaced with meters that can be read remotely, aiding consumption monitoring and conservation efforts. At present residents have been asked to water their gardens not more than twice a week; the new meters will be able to stop watering that takes place over more than two days in seven.
The system is a fixed-base radio read system, which connects via radio frequencies to cell phone tower monitors and then transmits the consumption data to a computer. The status of the cell phone towers can be monitored through Google Earth – a program that uses satellite imagery, maps, terrain and three-dimensional buildings to show live images of locations. The monitors also notify County personnel when meters have been tampered with, or when the presence of a leak is suspected.
Over 10,000 meters have already been replaced, and the benefits of the hourly reads are apparent to County officials and residents alike.
