style="text-indent:25px">浮筒液位計的構(gòu)造:浮筒液位計的主要由以下幾部分構(gòu)成：浮筒、連接件（鋼絲、固定卡）、扭力桿、扭力傳感變送器以及測量筒（外浮筒）等表體附件。浮筒是一個器壁很厚的金屬管兩端焊死，一端留有一個接口環(huán)為浮筒的上端。連接鋼絲是一個韌性好性變小的不銹鋼條，一端連接固定在浮筒拉環(huán)上，一端固定在扭力桿的固定卡上，把浮筒和扭力桿連接起來，是一個力的軟傳導(dǎo)部件。扭力桿是一個機(jī)械的扭轉(zhuǎn)臂，把連接鋼絲上由浮筒重力和液體浮力相互作用產(chǎn)生的拉力，轉(zhuǎn)換為繞軸轉(zhuǎn)動的軸位移。扭力傳感變送器對扭力桿臂上的軸位移進(jìn)行檢測處理轉(zhuǎn)換，然后與變送器內(nèi)部程序參數(shù)進(jìn)行運(yùn)算比較，計算得出此時的液位高度，顯示并輸出標(biāo)準(zhǔn)電流信號遠(yuǎn)傳。實現(xiàn)液體的液位檢測。靜壓投入式液位變送器（液位計）適用于簡單的調(diào)校和靈活的安裝方式為用戶輕松地使用提供了方便。溫州投入式液位計價格</p><p style="text-indent:25px">分體式超聲波液位計產(chǎn)品特點有哪些？溫州投入式液位計價格</p><p style="text-indent:25px">超聲波液位計的工作原理是通過一個可以發(fā)射能量波（一般為脈沖信號）的裝置發(fā)射能量波，能量波遇到障礙物反射，由一個接收裝置接收反射信號。根據(jù)測量能量波運(yùn)動過程的時間差來確定液(物)位變化情況。由電子裝置對微波信號進(jìn)行處理，行終轉(zhuǎn)化成與液位相關(guān)的電信號。一次探頭向被測介質(zhì)表面發(fā)射超聲波脈沖信號，超聲波在傳輸過程中遇到被測介質(zhì)（障礙物）后反射，反射回來的超聲波信號通過電子模塊檢測，通過**軟件加以處理，分析發(fā)射超聲波和回波的時間差，結(jié)合超聲波的傳播速度，可以精確計算出超聲波傳播的路程，進(jìn)而可以反映出液位的情況。溫州投入式液位計價格</p></p><br
