Data from the pitometer log is usually fed directly into the ship's navigation system.

While the pitometer log is very commonly used today, there are a number of other logs that are also in use.

Pitometer Logs: These devices provided an accurate measurement of the own ship's speed.

The basic technology of the pitometer log is similar to that of the pitot tube on an aircraft.

Pitometer logs (also known as pit logs) are devices used to measure a ship's speed relative to the water.

During World War II, pitometer logs were often interfaced directly into warship fire control systems.

Additional inputs to the Mark 1 were continuously generated from the stable element, a gyroscopic device that reacted to the roll and pitch of the ship, the pitometer log, which measured the ship's speed through the water, and an anemometer, which provided wind speed and direction.

Kurt glanced at the pit log.

Pitometer logs (also known as pit logs) are devices used to measure a ship's speed relative to the water.

Dahlman's firm had carried out geotechnical studies and reviewed maps, reports and borehole and test pit logs on adjacent sites from which the Dahlman Report concluded as follows:

More modern methods include pit log referencing engine speed (e.g. in rpm) against a table of total displacement (for ships) or referencing one's indicated airspeed fed by the pressure from a pitot tube.
