The Digibar V was designed to continuously measure sound velocity near the transducer array of Multibeam echo sounders. The Digibar V uses a 2 MHz transducer and time of flight circuitry sounding across a know distance to measure the sound velocity directly. The housing of the Digibar V was designed to allow for flexible attachment options in order to place the velocimeter near the Multibeam echo sounder’s transducer array.
