FIELD: measuring technology.
SUBSTANCE: weight of oil product (OP) released from a tank is calculated by means of a computer on base of volume determined in correspondence with a measured height of OP in the tank and also on base of temperature and density of OP in the tank. To check change of OP weight in the tank the weight of released OP is calculated with a computer on base of values obtained from sensors of temperature and volume installed on fuel and oil release pumps (FRP) and from sensor of density installed in pipeline supplying fuel from tanks to FRP; further, obtained values of consumption of OP in the tank and at FRP are compared and the comparing error of OP consumption in the tank is obtained in the result of comparison.
EFFECT: upgraded accuracy of measurement of volume of oil product at storage and at different modes of release and filling.
