style="text-indent:25px">影響電子流量傳感器的因素較多，原理有十余種，類型不少于200種，有人對現(xiàn)場千余臺流量傳感器進行了調(diào)查，發(fā)現(xiàn)其中60%所選擇的方法不太合適，而即使選擇的方法合適，又有約一半以上在安裝和布局上有問題。正確選擇，并非易事。歸納起來，正確選擇流量傳感器取決于六個因素：傳感器技術(shù)參數(shù)、流體特性、流動的狀態(tài)、安裝、環(huán)境、經(jīng)濟性。超聲流量傳感器的流量測量準確度幾乎不受被測流體溫度、壓力、粘度、密度等參數(shù)的影響，又可制成非接觸及便攜式測量儀表，于是可以解決其它類型儀表所難以測量的強腐蝕性、非導電性、放射性及易燃易爆介質(zhì)的流量測量問題。</p><p style="text-indent:25px">電子開關(guān)的信號自動分段技術(shù)是經(jīng)過對現(xiàn)場信號多次模型分析，采用信號自動分段技術(shù)與模型識別技術(shù)從而能有效的克服壓力波動等各種干擾，提高壓力開關(guān)的可靠性。信號自動分段方法的基本原理是選用一個固定的窗選取平穩(wěn)運行的信號作為參考段，不斷與當前信號作比較，非平穩(wěn)性（如上站停泵引起的信號特性的變化）可以由不同段之間的過程統(tǒng)計特性和頻譜性的改變顯示出來。一般根據(jù)幾種判據(jù)，當判據(jù)大于一定的閾值或當前段低于設定值時，就認為信號進入了另一段（異常段）。如果安裝孔的尺寸不合適，電子壓力傳感器在安裝過程中，其螺紋部分就很容易受到磨損。</p><div

K--流量計的儀表系數(shù)，脈沖數(shù)/m3（P/m3）。由上式可以看出流量傳感器的輸出頻率只于旋渦發(fā)生體及管道的形狀尺寸等有關(guān)。電子元件輸出相應的脈沖信號反饋給控制器，由控制器判斷水流量的大小，調(diào)節(jié)控制比例閥的電流，從而通過比例閥控制燃氣氣量，避免燃氣熱水器在使用過程中出現(xiàn)夏暖冬涼的現(xiàn)象。為了避免損害電子壓力開關(guān)的器件，要在說明書范圍內(nèi)才能夠正常使用。電子壓力繼電器安裝</p><p
