The invention discloses a fuzzy weighing pressure difference compensation method for a charging tank of a serial-tank bell-less top. According to the method, weighing pressure difference compensation coefficients of the charging tank are subjected to on-line fuzzy modeling by using pressure and charging tank weighing data which are acquired in the primary pressure equalization process and secondary pressure equalization process of the charging tank in real time, so as to obtain a non-linear physical relationship of the difference between the top pressure and the charging tank pressure and the weighing pressure difference compensation coefficients of the charging tank; due to a calculation model of the weighing pressure difference compensation coefficients of the charging tank of the serial-tank bell-less top, the technical problem that the pressure difference compensation coefficients are shifted because of external factors of the blast furnace is effectively solved; as the calculation model of the weighing p
