contenttypeSummary

The Doppler log measures speed through water by using the Doppler effect of sound signal reflected from the seafloor or from suspended matter in the water column. Two transducer are installed in the ships keel and can be alternatively used. Hydroacoustic frequency amounts to 270 kHz.
