Abstract

At present, many companies and organizations need to store fuel or other liquids for their own needs. The classic option for determining the capacity of tanks is to fill them with liquid, using a liquid quantity meter, the error of which is determined before calibration for a given filling speed. This method is reliable because it all depends on the accuracy of the meter. The principle of operation is simple: a tube with a meter is used to supply liquid to fill the tank to the limit of filling height. The value calculated by the meter and is the volume of liquid in the tank. But this method requires a significant amount of time and fluid to conduct the experiment and in practice is not always possible to implement. An alternative is to use a laser scanner to scan the inner surface of the tank. Its volume is calculated on the basis of the obtained arrays of surface points. This article will consider the method of determining the capacity of tanks, which uses the results of laser scanning of the inner surface, and takes into account the geometric characteristics and features of the tank, including maximum filling height, maximum depth of depressions, temperature values during scanning and linear temperature coefficient of expansion of the tank material.
