ADV Sampling Volume Size and Velocity Accuracy

ADV Sampling Volume Size and Velocity Accuracy

The SonTek ADV is a single point, high resolution Doppler current meter which provides 3-D velocity measurements in a remotely sampled volume. The ADV is a bistatic Doppler current meter. The term bistatic refers to the fact that the ADV uses separate acoustic transducers to transmit and receive sound energy. The ADV transmitter generates sound with most of the energy concentrated in a tight cylindrical volume, while the receivers are the most sensitive to sound coming from a slightly broader angular range.
