Zusammenfassung:	To provide a water use state monitoring system capable of realizing abnormality detection operation and watching operation suitable for tap water use places respectively, on the basis of a water use state at each tap water use place.SOLUTION: A water use state monitoring system 1 for centralized monitoring of a water use state of each tap water use place 2 includes: meter reading devices 5 installed at the tap water use places respectively; and a center device 4 including a management server 40 performing two-way communication via a general communication network 3 between the meter reading devices 5. Each of the meter reading devices 5 includes an electronic water meter 6 and a transmitter 8. The electronic water meter 6 is provided with: meter reading parts (62, 63, 64) of a water use amount; and an abnormality detector 74 for detecting an abnormal state by comparing a meter reading result of the meter reading parts with a predetermined detection condition. The management server 40 of the center device 4 includes an abnormality detection condition change function 47 for changing a detection condition to become a reference of detection of an abnormal state in the electronic water meter 6, via the transmitter 8.SELECTED DRAWING: Figure 2 【課題】各水道水使用場所での水使用状況に基づき、水道水使用場所のそれぞれに適した異常検出動作および見守り動作を実現可能な水使用状況監視システムを提供すること。【解決手段】各水道水使用場所２の水使用状況を集中監視する水使用状況監視システム１は、水道水使用場所のそれぞれに設置される検針装置５と、これらの検針装置５との間で一般通信回線網３を介して双方向通信を行う管理サーバ４０を備えたセンター装置４とから構成される。各検針装置５は、電子式水道メータ６および送信機８を備えている。電子式水道メータ６は、水道使用量の検針部（６２、６３、６４）、および、検針部の検針結果を予め定めた検出条件と比較して異常状態を検出する異常検出部７４を備えている。センター装置４の管理サーバ４０は、送信機８を介して、電子式水道メータ６における異常状態の検出の基準となる検出条件を変更する異常検出条件変更機能４７を備えている。【選択図】図２
