Abstract
【解決手段】入口14と、第二室17と流体的に連通した出口16とを有する第一室12であって、かつ層流を形成する要素を有し、第一室の出口には、第二室に通じかつ一連の小滴を解放するように寸法決めされた小滴生成器が設けられ、小滴の各々は、小滴生成器のオリフィス中の液体から自重で形成しかつ剥離する、第一室と、二つの室の気圧を均等にするために第一室の上側領域と第二室の下側領域の間で延びている溢流導管21と、小滴生成器から出る各小滴の通過を数えるために小滴生成器の下に第二室内に位置決めされている電子手段28と、全流出量、開始時間、単位時間当りの流出量、液体の導電率、経過時間及びこれらの組み合わせからなる群から選択された情報を受け取りかつ記録する電子手段に接続されている情報処理ユニット30とを備えた低流量測定装置を提供する。
【選択図】図1
Description
a)入口と、第二室と流体的に連通した出口とを有する第一室を備え、前記第一室は、層流を形成する流量制限要素を有し、第一室の出口には、第二室に通じかつ一連の小滴を解放するように寸法決めされた小滴生成器が設けられ、小滴の各々は、流量制限要素によって送られた小滴生成器のオリフィス中の液体から自重で形成しかつ剥離する、第一室と、
b)二つの室の気圧を均等にするために第一室の上側領域と第二室の下側領域の間で延びている溢流導管と、
c)小滴生成器から出る各小滴の通過を数えるために小滴生成器の下に第二室内に位置決めされている電子手段と、
d)情報を受け取りかつ記録するため、かつ連続した小滴の間の時間間隔を計測し、かつ連続した小滴の間の時間間隔の関数としての小滴寸法の変化を処理しつつ液体の流量及び全体積を計算するために、電子手段に接続されている情報処理ユニットとをさらに備えた低流量測定装置を提供することによって、前述の目的を実現する。
a)垂直管116は、室の上部120と下部122の気圧を均等にし、それにより矛盾のない読取りを行なうのに有用である。
b)垂直管116はフィルタカップ114を支持する。
c)垂直管116は、装置は意図していない速い流れを装置が受ける場合において、溢流管として機能することによって上室120が充満するのを防ぐ。
