  • Page 45 Transducer installation principles Use a suitable inclination angle In order to ensure laminar flow, the transducer face may be tilted slightly upwards in relation to the water flow. This allows the flowing water to meet the face directly, and assures laminar flow. Use a suitable toe-in angle The primary consideration for any transducer installation must be to allow laminar water flow.

  • Page 53: Transducer Installation Using Drop Keel

    Transducer installation principles Transducer installation using drop keel If your vessel is fitted with a drop keel, this is a superior platform for the ES38-18/200–18C transducer. Drop keels are often used on larger research vessels. A drop keel will frequently protrude as far as three meters below the hull.

  • Page 58: Introduction

    Mount the transducer deep In order to achieve the best possible ES38-18/200–18C performance, mount the transducer as deep as possible under the vessel’s hull. Consider the situations when the vessel is unloaded, and when it is pitching in heavy seas.

  • Page 59: Avoid Protruding Objects

    Choose a position far away from the bow thruster(s) Bow thruster propellers are extremely noisy. When in operation, the noise and cavitation bubbles created by the thruster may make your ES38-18/200–18C system useless, almost no matter where the transducer is installed. 404776/A...

If your vessel is pitching, the tunnel may be filled with air or aerated water in the upper position and release this in the lower position. In general, all transducers must therefore be placed well away from the bow thruster. In most cases, a location forward of the bow thruster is advantageous.
