Area velocity sensor
The submersible area velocity sensor uses advanced Pulse-Coherent cross-correlation technology. The velocity profile of the entire cross-section is captured in up to 32 measurement cells, providing best-in-class resolution of flow. The sensor measures both flow velocity and water level in order to calculate total flow volume. The integrated temperature sensor is used for automatic data correction and provides enhanced statistical information, e.g. for infiltration studies.
With its dimensions of only 19 x 24 x 129 mm, the area velocity sensor causes no interference in the flow profile, which results in more accurate velocity measurements, especially in low-flow situations.
