11.11.2 Determining the position for the transducers

The CA40/42/50/52 is a sophisticated piece of electronic equipment, but how

well it will perform under actual operating conditions will be largely dependent

upon the location of the transducer and how it has been installed.

Careful consideration, therefore, must be given to selecting the mounting location

and on deciding the method of installation that best suits the vessel.

Air bubbles and turbulence caused by the vessel’s movement through the water

will seriously degrade the transducer’s performance. Therefore the transducer

should be located well clear of any water intake or discharge line and also clear

of any projection along the hull line which might disturb the smooth flow of

water.

It is of profound importance for good performance of the CA40/42/50/52 that the

water flowing over the transducer be free of bubbles and aeration. If the trans-

ducer face is clean but the performance degrades with increasing vessel speed,

then aeration of the water flowing under the transducer may be the cause of the
