The present invention relates to a measuring device and its implementation method, which is used to confirm the switch on/off state of a cover body arranged on a can body. The cover body can be moved away from the can body by a manner of rotation or pulling-apart, and at the same time an electronic module configured in the cover body can be used to detect the moving-away state of the cover body. Finally, when the cover body is completely moved away from the can body, the electronic module transmits messages to an apparatus.本發明係有關一種測量裝置,以及其執行方法,其為確認一蓋體設於一罐體之開關狀態,其可以依據該蓋體以旋轉或拔離方式移離該罐體,同時依設於該蓋體之一電子模組偵測移離該蓋體狀態,最後當該蓋體完全移離該罐體,該電子模組傳輸訊息至一設備。1‧‧‧測量裝置30‧‧‧罐體31‧‧‧蓋體311‧‧‧螺紋60‧‧‧設備
