The sound scanner is a device used for measuring the depth of waters. In its simplest form, the scanner consists of a lead weight tied to the end of a rope. Nowadays, secondary factors are also used in measurements made with the scanner. Thus, besides the scanner, sound waves and radio waves directly influence the measurement.
To achieve more precise measurements in deep waters, attention must be paid to certain details. For this reason, sound scanners come in several variants to facilitate the measurement process. The sound scanner, which occupies a large space on motor and sailing ships, has existed for a long time.
Movement is ensured through the propeller on the scanner, and thus the measurement takes place. According to this principle, the propeller rotates under the pressure of the water when the weight descends to the bottom of the water, and the gears attached to the propeller move an indicator that provides the measurement.
Sound scanners, which are extremely important for ships, also appear in other fields of use. In particular, you can frequently see them in places where measurement and sound clarity are important. Generally, sound scanners can be found in theaters, cinemas, concert halls, and other spaces requiring sound insulation. For the proper adjustment of sound insulation and echo, sound scanners are on the list of essential equipment.
Scanners have a history of over two thousand years. Even today, ships need the support of scanners. Generally, these scanners that facilitate measurement come in three types. Below you can see the types and characteristics of the scanners.
What are the types of sound scanners?
Scanner for small boats (Filika iskandili): This type of scanner is generally used in shallow waters and on small boats. The length of the rope is 10 fathoms (18.3 m), and the weight is 3 kg.
Manual scanner (El iskandili): This type of scanner is frequently used on all types of ships when entering ports. The length of the rope is 25 fathoms (46.25 m), and the lead weight is between 4.5 and 6.5 kg.
Deep water scanner (Derin su iskandili): The deep water scanner is a type used before and after the introduction of the scanning machine. It is especially used on defective ships. The length of the rope is 100 fathoms (183 m), and the weight is between 13 and 13.5 kg.
