                                                                                                                                                                                                            一.雷達水位計

                                                                                                                                                                                                     雷達水位計天線發射極窄的微波脈沖,這個脈沖以光速在空間傳播,遇到被測介質表面,其部分能量被反射回來,被同一天線接收。發射脈沖與接收脈沖的時間間隔與天線到被測介質表面的距離成正比。由于電磁波的傳播速度極高,發射脈沖與接收脈沖的時間間隔很?。{秒量級)很難確,XYRD8X雷達水位計采用一種特殊的解調技術,可以準確識別發射脈沖與接收脈沖的時間間隔,從而進一步計算出天線到被測介質表面的距離。 水位計的設計使用依據并參考國家GB T11828 水位測量標準及SL/T243-1999水位計通用技術條件。

                                                                                                                                                                                                         二.投入式液位計

                                                                                                                                                                                                    投入式液位計是一種線纜式液位計UHF-LT 投入式變送器是基本所測液體靜壓與該液體液位高度成正比的原理 P=p gh,采用擴散硅原理壓力敏感元件,將靜壓裝換成電信號。經過溫度補償和線性矯正。轉換成4-20mADC標準電流信號輸出。

                                                                                                                                                                                                        三.超聲波液位計

                                                                                                                                                                                                             超聲波液位計是通過換能器(探頭)發出高頻超聲波脈沖,該聲波遇到被測液位表面被反射回來,部分反射回波被換能器(探頭)接收并轉換成電信號。超聲波液位計就是利用聲波發射與接收的時間差,以及聲波傳播速度來計算液面高度的。采用無接觸測量技術的超聲波液位計,能穩定可靠地應用于各種敞開式槽池中的連續性液位測量。
