1、液體比重不同時(shí)，浮球的動作位置將會有所變動，一般SG比水小時(shí)，浮球浸在液體中部分將相對增多；2、產(chǎn)品參考比重以水（SG=1）所以使用時(shí)在選用浮球時(shí)須考慮液位的比重SG，一定大于浮球規(guī)格所標(biāo)示，否則，浮球開關(guān)無法浮動； 3、粘度高不會干涸的液體，一般應(yīng)選用外徑較大的浮球；4、使用磁鐵來感應(yīng)磁簧開關(guān)，因此被測液位應(yīng)無鐵屑，否則會影響浮球?qū)﹂_關(guān)的正確動作。小型浮球液位開關(guān)是一種、結(jié)構(gòu)簡單，使用安裝方便的液位控制器。它沒有復(fù)雜的電路，不會受到干擾，使用磁簧開關(guān)不需要提供電源即可工作并且接點(diǎn)壽命可達(dá)200萬次。它設(shè)有復(fù)雜的電路，不會受到干擾，只要材質(zhì)選擇正確，任何性質(zhì)液體、壓力、溫度皆可使用。壓差式液位開關(guān)訂購</p><p
