According to Gerry Harrington, Director of Sales and Marketing with Spire Metering Technology, improved flow measurement is primed to have a growing impact on reducing water loss across the entire water distribution network.
As Harrington points out in this Water Online Radio interview, older mechanical meters are unable to record very low flow rates because they require some level of inertial movement from the water to activate their moving parts. This means that a lot of water at low flow rates can leak out and fail to be measured. Ultrasonic flow meters without moving parts can measure far lower flow rates and help identify these leaks.
Harrington goes on to explain the difference between transit time flow measurement and the use of ultrasonic Doppler technology, listing the suitable applications for each.
