7ML5221西門子超聲波液位計是目前世界上精度好的超聲波液位計。

SITRANSProbeLU是兩線制回路供電的超聲波變送器，用于測量儲罐和簡單過程罐中液體的高度和體積，以及明渠流量。SITRANSProbeLU是水和污水處理行業(yè)及化學儲罐中液位測量的理想選擇。
SITRANSProbeLU的測量范圍為6m或12m。使用了消除固定障礙物干擾的虛假回波自動抑制功能、更高的信噪比、高達測量范圍的0.15%或6mm的度──ProbeLU提供了的高可靠性。
SITRANSProbeLU不但采用了延續(xù)自聲名的MilltronicsProbe的聲智能信號處理技術，同時也結合了新的回波處理技術以及新的微處理器和通訊技術。
ProbeLU的換能器可選用ETFE或PVDF材質，以適用所應用場合的化學工況。同時，對于物料和過程溫度變化的應用場合，ProbeLU采用內置的溫度傳感器以補償溫度的變化。

ProbeLU西門子一體化超聲波物位計使用標準西門子紅外手操器，在危險區(qū)域不必開蓋即可安全操作。
