Zusammenfassung: | To provide a water meter to which is added a wireless communication function in such a way as to suppress a dimensional increase.SOLUTION: An electronic measurement unit 4 of a water meter 1 includes an upward protrusion 40 that protrudes upward from a meter case 2. A wireless communication unit 8 is removably attached to the meter case 2 so that the upward protrusion 40 is inserted from lower side into an annular part center hole 82. The wireless communication unit 8 is arranged within a protruding dimension from the meter case 2 of the upward protrusion 40 and the front-back length dimension of the mete case. Dimensional increases in the vertical and front-back directions of the water meter 1 having had the wireless communication unit 8 attached thereto can be avoided. The wireless communication unit 8, by being removed from the meter case 2, does not obstruct the installation work, etc. of the water meter 1. It is possible to install the wireless communication unit 8 alone at a place where receive sensitivity is good, and to perform wireless communication without being affected by the installed place of the water meter 1.SELECTED DRAWING: Figure 1
【課題】寸法増加を抑制可能な形態で無線通信機能が付加された水道メータを提供すること。【解決手段】水道メータ1の電子式計測ユニット4は、メータケース2から上方に突出した上方突出部40を備えている。無線通信ユニット8を、環状部中心穴82に下側から上方突出部40が挿入された状態となるように、メータケース2に着脱可能に取り付ける。上方突出部40のメータケース2からの突出寸法内およびメータケースの前後方向の長さ寸法内に、無線通信ユニット8が配置される。無線通信ユニット8を取り付けた水道メータ1の上下方向、前後方向の寸法増加を回避できる。無線通信ユニット8は、メータケース2から外すことで、水道メータ1の設置工事等において邪魔にならない。無線通信ユニット8のみを受信感度の良好な場所に設置でき、水道メータ1の設置場所に影響されずに無線通信を行える。【選択図】図1 |
