The present invention relates to the failure to prevent the water level meter, independently of the water level meter, the combination of the container to determine the water level to provide a water level meter pipe with cap filter that can be freely A mouth to open and close the cap 2 on the water level gauge pipe body 1 is provided, the filter 3 is provided in the mouth of the bottom, to prevent the entry of foreign objects such as sand into the pipe 1, pipe 1 the inside so as to not interfere with the water level gauge 7 is moved up and down smoothly, help so choose a container combine examine the water level by an independent integrated with the water level gauge 7 of failure preventionFIELD 2【課題】水位計の故障防止をし、水位計が独立して、水位を調べる容器との組み合せが自由にできるキャップ・フィルター付水位計用パイプを提供する。【解決手段】水位計用パイプ本体1の上の口に開閉キャップ2を設け、下の口にフィルター3を設け、パイプ1内への砂などの異物の侵入を防ぎ、パイプ1内を水位計7がスムーズに上下に移動するのを妨げないようにして、水位計7の故障防止と独立一体化をさせて水位を調べる組み合わせる容器を選べるようになるのに役立つ。【選択図】図2
