PROBLEM TO BE SOLVED: To provide a measurement device, a measurement method, and measurement program in which a supply amount of liquid is controlled while suppressing cost increase of facility using a tubular structure.SOLUTION: A measurement device 1 has: a detection part 2 which detects pressure corresponding to a shape change of a tubular structure whose shape changes corresponding to a supply amount of liquid flowing inside the structure； a time-specifying part 3 which specifies supply time during which liquid has been supplied on the basis of a pressure detected by the detection part 2； and a supply amount calculation part 4 which calculates a supply amount of liquid on the basis of the supply time.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】管状構造物を用いた設備のコストの上昇を抑制しつつ、液体の供給量を管理する、計測装置、計測方法、及び計測プログラムを提供する。【解決手段】内部を流れる液体の供給量に応じて形状が変化する管状構造物の形状変化に応じた圧力を検出する、検出部２と、検出部２が検出した圧力に基づいて、液体が供給されていた供給時間を特定する、時間特定部３と、供給時間に基づいて液体の供給量を算出する、供給量算出部４と、を有する計測装置１である。【選択図】図１
