五、發明說明（7) 經濟部智慧財產局員工消費合作社印製 也1生，流體管線204末端208處的壓力則可能與海拔高度 差有關，因為在膜基礎式系統中，撓性膜3〇3及313係以 彈性能量方式來儲存部份的pV功而使得處於平衡的膜之 間具有略為不同的壓力，所以相關聯性彳艮複雜。因此，本 5發明係在量測相對海拔高度之前先行提供測量、相關聯性 以及關係的發展。若沒有此等相關聯性，相對海拔高度的 估异值可能具有高達8至1〇吋的誤差，本發明人已經發 現··此等系統中之新的膜表現出磁滯作用，此磁滯作用似 乎Ik著膜的反覆固定而遞減，因此，可在將膜予以撓屈的 10其他啟動程序完成之後進行校準。 參照圖2之各種標示物件，在程序4〇1中校準至少 一個泵300或310中之壓力。程序402中，在至少一個泵 300或310與管線204之間建立流體導通。在程序4〇3中 量測與管線相導通之泵中的靜壓力，並在程序4〇4中估算 15管線與流體流動控制裝置之間的相對海拔高度，可利用= 中所量測的靜壓力並利用-高度差與壓力差之間的一已知 關係（譬如每25公厘汞柱〇·3公尺（卜尺））來達成此作° 用。最後，可調整泵壓力以容納程序4〇5中的高度差。 圖5(a)係為突顯出根據本發明的一項實施例採用圖 20 2的流體流動控制系統之啟動及校準之方塊圖，因為任二 容積或兩容積可在先前程序中呈部份充滿狀，在程序 中將液體容積302及312排空，排空兩液體容積3〇2及 312之後，程序502中將出口閥3〇6及316均予以關閉。 在程序503中以流體藉由重力充注兩個液體容積3〇2及 (請先閱讀背面之注意事項再填寫本頁)
