Abstract
A dynamic pressure log to which is connected a device for electronic further processing and correction of the measured values is used to measure the speed of ships. The differential pressure measuring instrument (10) is arranged at the input (8) of a flow duct (7), the static and total pressure being measured approximately at the same location. The measured differential pressure is transmitted electrically to an adjusting unit (22), where it is converted into values corresponding approximately to the speed. These values are corrected in a following correction unit (23), e.g. in accordance with the flow conditions in the case of a circular course, or with the rudder position. The corrected speed value is displayed and used to calculate as a function of time the distance travelled and, as the case may be, to record the route travelled. <IMAGE>
