METHOD OF MEASURING SPEED OF UNDERWATER OBJECT MOVEMENT Russian patent published in 2018 - IPC G01P3/64 

FIELD: measuring equipment.

SUBSTANCE: invention can be used for the certification of variable pressure basins as testing equipment, pilot testing of starting devices of uninhabited small-size underwater vehicles, hydrodynamic testing of full-scale and model underwater objects. Essence: electric signal of potentiometric sensor is digitized and recorded in the form of a time series with a frequency providing the required accuracy in measuring the speed of rectilinear motion of underwater object that is mechanically coupled to the said sensor using a cable and tackle using one of the circuit versions that takes into account the required accuracy of measuring the speed of motion of underwater object, the time series is transformed into values of increments of displacements and value of increments of time, local speeds and average speed of the object are determined.

EFFECT: measuring the speed of underwater object with guaranteed high accuracy without loss in reliability and ease of implementation of the method and operation of the device for its implementation.
