Zusammenfassung: | To provide a liquid supply system capable of preventing theft of a liquid inside a storage tank or of the storage tank itself, mischief to the liquid inside the storage tank, or the like, in a liquid supply device.SOLUTION: A liquid supply system comprises: a liquid supply device including a storage tank provided on the ground for storing a liquid, a nozzle for supplying the liquid to a liquid-supplied unit, a liquid supply channel whose one end is connected to the storage tank and the other end is connected to the nozzle, a pump provided in the liquid supply channel for pressure-feeding the liquid from the storage tank towards the nozzle, and a supply amount measurement means provided in the liquid supply channel for measuring a supply amount of the liquid pressure-fed by the pump from the storage tank towards the nozzle; a weight measurement means for measuring a weight of the liquid supply device; a detection means for detecting whether or not the liquid is being supplied by the liquid supply device; and a determination means for determining a presence/absence of abnormality in the liquid supply device, based on a detection result by the detection means and the weight measured by the weight measurement means.SELECTED DRAWING: Figure 5
【課題】液体供給装置における貯蔵タンク内の液体或いは貯蔵タンク自体の盗難や貯蔵タンク内の液体へのイタズラ等を防止することが可能な液体供給システムを提供する。【解決手段】地上に設けられ、液体を貯蔵する貯蔵タンクと、被液体供給体に液体を供給するノズルと、一端が貯蔵タンクに接続され、他端がノズルに接続される液体供給経路と、液体供給経路に設けられ、貯蔵タンクから液体をノズルに向けて圧送するポンプと、液体供給経路に設けられ、ポンプにより貯蔵タンクからノズルに向けて圧送された液体の供給量を測定する供給量測定手段と、を有する液体供給装置と、液体供給装置の重量を計測する重量計測手段と、液体供給装置による液体供給が行われているか否かを検出する検出手段と、検出手段による検出結果と重量計測手段により計測される重量とに基づき、液体供給装置の異常の有無を判断する判断手段と、を備える。【選択図】図5 |
