In connection with a method for calibrating cylindrical tanks for determining the volume thereof, it is suggested to establish a number of survey stations (A, B, C) for the fixing of a base polygon by measuring the distance between said stations and the angles therebetween. From a first survey station (A) there are established directions, level by level, to a first tankwall profile (T) and a second tankwall profile (T), as well as the direction to a second survey station (B) for orientation in the base polygon (A, B, C). Corresponding measurements are taken from the other survey stations for on the basis of the direction observations to determine the angle (TAT) between every pair of tankwall profiles at the same level, so that for every level there can be calculated a mean radius (r0), which constitutes the basis for the calculation of volume. |
