Area velocity sensor

The submersible area velocity sensor uses advanced Pulsed-Doppler technology to directly evaluate velocity profiles. The sensor measures both flow velocity and water level in order to calculate total flow volume.

With its dimensions of 15 x 25 x 108 mm, it is the smallest sensor of this type currently available. Its low profile means less interference, which results in more accurate velocity measurements, especially in low-flow situations.
