Technology & Benefits

Acoustic Phase-Shift Transit-Time Technology

    • Eight transducers define four acoustic transit-time paths
    • Accurate even near surface and seabed
    • Accurate low- and high-velocity measurement
    • Measures very clear as well as turbid water (no reflectors required)
    • Economical 2 or 3 dimensional point velocity(X,Y converted to N,E using compass/tilt sensors)
    • Internal recording and real-time output

Optional CTD for salinity/sound velocity
