Inside the sensor are four piezoelectric ceramics which emit short pulses along narrow acoustic beams pointing in different directions to measure velocity. A fifth ceramic is mounted in the centre of the sensor, and aimed vertically, is used to measure depth. Each acoustic beam measures velocity at multiple points in the water column. Each measured velocity data point is very precise to within 0.01ft/s.
This distribution of accurate velocity measurements is then used to determine the flow pattern over the entire cross-section of flow. Since the flow pattern and measured velocity distribution are dependent on each other, the ADFM?s advanced flow algorithms automatically adapt to changing hydraulic conditions within the pipe. This insures accurate flow rate measurement over a host of different measurement environments and hydraulic conditions. This also removes the need for in-situ calibration.
The data logging, signal processing and data output electronics are all housed in the ADFM enclosure. The enclosure is available as a NEMA 4X Box housing which is suitable for wall or console mounting in permanent applications, or a NEMA 6P cylindrical housing for use in manholes or other "wet" environments.
