PROBLEM TO BE SOLVED: To provide a discharge control device for a metering discharge system capable of flexibly coping with differences in material characteristic and the environment or with aged deterioration of materials, and being easy to handle on site without requiring a procedure such as a preliminary experiment. SOLUTION: Processes for correcting discharge pressure P and discharge operations are repeated at certain intervals; during a first period of time T1, a process 110 for moving a material barrel 5 to a weighing position, a process 120 for discharging viscous material, a process 130 for measuring the discharged weight W, and a process 140 for the initial correction of the discharge pressure P are carried out. After the process 110 for moving the material barrel 5 to a working position, the first discharge operation 150 is carried out. During a second period of time T2 after the elapse of a certain period of time or after the completion of a certain number of discharges, the process 110 for moving the material barrel 5 to the weighing position, a process 120 for discharging liquid material, the process 130 for measuring the discharged weight W, and a process 160 for the intermediate correction of the discharge pressure P are carried out. After the process 110 for moving the barrel 5 to the working position, the second discharge operation 150 is carried out. Similarly, the same processes as those carried out during the second period of time are repeated up to an n-th period of time Tn.
