For many years, ultrasonic metering has been utilized for large scale liquid and gas measurement. However, it is a relatively new technology for small meter applications — particularly those designed for potable water. This paper outlines ultrasonic metering operating principles and the use of this technology by utilities in small water meter applications. Also included is a discussion regarding the Badger Meter E-Series® ultrasonic meter and its suitability for these applications.
Mechanical meters have been used in the water industry for more than 150 years. In recent years, a number of electronic metering technologies have emerged. One of these advancements, the ultrasonic flow meter, was initially introduced in the early 1960s for industrial applications.
