3. Installation
3.1. Optimal Orientation
For ROV installation always mount the altimeter so that it is as close to the true vertical as
possible in relation to the trim position of the vehicle. The transducer head should be clear
of any obstruction and away from possible sources of interference, such as the wake from
thrusters or from electrical devices that may have high electromagnetic emissions. Errors in
the head alignment can give rise to unreliable results.
3.2. Mounting Material and Suitable Brackets
Caution
Avoid any metal alloys containing copper such as brass or bronze.
Non-metallic clamps should always be used where possible to prolong the life of the unit and
prevent any galvanic corrosion effects. If metallic clamps are used they should be electrically
insulated from the sonar body by means of rubber or plastic strips or mount brackets of at
least 3mm thickness and extending at least 3mm beyond the clamp boundary. They should
also be painted or lacquered with at least three coatings.
3.3. Dual Frequency Altimeter
3.3.1. Orientation
The shape of the echosounder is designed
with hydrodynamics in mind. The front of
the echosounder is at the opposite side
to the Tritech connector which is provided
protection from water flow by the mounting
bracket.
