Transducer
Transducer is a key part in the system as it is a precise sensor. It is must be carefully protected when transport and install. No huge pressure allowed to be
acted it. Working in the air or dropping to ground can damage it. Less effective
may be occurred when paints and duty hanging on its surface or incorrect
installation.
Sometimes two transducers can be selected to install the head and buttock if the vessel is too long or sidelong.
It should be installed flat surface far away source of vibration and water current. Transducer should be vertical. One cover using lead water current maybe
installed to less water current effect on transducer when necessary.
Transducer cannot be left from water and touch air while working, or will be damaged.
It should be at least 50cm deeper under water but flat with keel.
