    一、導波雷達液位計概述
    導波雷達液位計鍋爐是工業領域廣泛應用的設備,尤其是煉油行業,每個大型煉油廠都有十幾臺中壓鍋爐。鍋爐是高溫高力容器,屬于比較危險的設備,一旦高溫高力蒸汽泄漏容易造成人員傷害。鍋爐汽包上所使用的導波雷達液位計是鍋爐的一個關鍵設備,汽包內的液位就靠它來觀測,有人稱它為鍋爐的“眼睛”,如果“眼睛”有問題,鍋爐設備及供汽系統就處于危險狀態,所以如何選好用好鍋爐汽包液位計就成了每個鍋爐主管人員的首要問題之一。
    目前在鍋爐汽包上最常用的導波雷達液位計(水位計)主要有三種:石英管式液位計、磁翻轉液位計和高壓玻璃板式液位計。在高壓鍋爐汽包上主要使用高壓玻璃板式液位計,其中包括高壓雙色玻璃板式液位計和牛眼式雙色液位計,而高壓磁翻轉液位計在國內外都也有使用,但所占的比例較小。在中壓鍋爐汽包上主要使用石英管式液位計和磁翻轉液位計,高壓玻璃板式液位計因價格昂貴、泄漏點多、維修困難已逐步退出中壓鍋爐領域。
