原理，結構

智能電磁流量計是一種電磁感應式流量儀表，它由傳感器和智能信號轉換器組成。它能測量各類導電液體的體積流量，所測量的介質包括酸、堿、鹽等強腐蝕性液體,原水，冷卻水等導電液體及固液兩相液體                                                                               

特點

"流量傳感器的測量管道內無阻流件，沒有壓力損失。在測量導電液體介質時，只要合理選擇內襯和電極材料，就能正常計量，并不受流體的密度、粘度、溫度、壓力和電導率變化的影響，故測量準確度高。

應用                                                                                   

應用于石化、鋼鐵、電力、冶金、紡織、食品、制藥、造紙等行業(yè)及市政環(huán)保、水利等領域
