Zusammenfassung:PROBLEM TO BE SOLVED: To lessen a residual quantity as small as possible when taking viscous fluid out of a vessel. SOLUTION: The invention attains the object by a method of reducing the residual quantity in transfer of the viscous fluid which is characterized in that the residual quantity of the viscous fluid is detected by providing a method of supplying the viscous fluid with at least one of detection of a rising or lowering speed change of a pump shaft, detection of a pressure change after a pump outlet and detection of a lowering amount of an elevator pump and that switching is instructed based on an output of the detection.
