Anti-tilt weighing device and method for storage tank

The invention provides an anti-inclination weighing device of a storage tank. The anti-inclination weighing device comprises a main control device and three weighing assemblies which are arranged below three supporting legs of the storage tank in a one-to-one correspondence mode. The weighing assembly comprises a top plate, a weighing module, a bottom plate, a bolt, a pressure measuring gasket, an upper nut and a lower nut; and the main control device is connected with each pressure measuring gasket and each weighing module respectively. The invention further provides an anti-inclination weighing method of the storage tank, and the method comprises the steps that the main control device calculates the inclination state of the storage tank according to the pressure data of each pressure measuring gasket, and the inclination state comprises the inclination direction and the inclination angle of the storage tank; the main control device calculates the accurate weight of the storage tank according to the inclinat
