Underwater Log Rodmeter

Underwater Log Rodmeters are instruments used in navigation to measure the speed and distance traveled by a vessel through water. They are specifically designed for underwater use and are commonly used in marine and naval applications.

These log rodmeters are part of the supply class Navigational Instruments, which includes various instruments used for navigation purposes. They are categorized under the supply group Instruments And Laboratory Equipment, which encompasses a wide range of instruments used in laboratories and scientific research, including navigational instruments.

Underwater Log Rodmeters typically consist of a rotor or impeller that rotates as water flows past it. The rotation of the impeller is then converted into speed and distance measurements, which are displayed on a dial or digital screen. These measurements are crucial for determining the vessel's speed, distance traveled, and other navigational parameters.

The log rodmeter is usually mounted on the hull of the vessel, below the waterline, to ensure accurate readings. It is connected to the vessel's navigation system, allowing the data to be integrated with other navigational instruments and systems.

Overall, Underwater Log Rodmeters play a vital role in navigation, providing accurate and reliable speed and distance measurements for vessels operating in water environments.
