無運動部件，頻率和4至20毫安輸出，免維護
MFS磁感應流量傳感器是一種緊湊、低成本的槳輪傳感器的替代品。與帶有運動部件的傳感器不同，MFS可用于處理污染介質的應用。該系列提供可靠的測量技術、無障礙管道橫截面以及快速響應時間，使該系列成為無干擾操作的理想選擇。液體的溫度、密度、粘度、濃度或電導率的任何變化都不會影響磁感應式流量傳感器的輸出信號。除了使用壽命長外，這一系列產品非常適合于精確可逆測量封閉管道中導電液體的體積流量。
工作原理
測量管處于磁場中。如果具有一定流量的導電介質通過管道，它將以與磁場成直角的方向通過，從而產生一個與平均流速成比例的電壓，并由MFS內的兩個電極拾取。可獲得與流量成比例的頻率輸出信號（可提供模擬輸出選項）。
產品應用
導電液體流量監測導電液體噴灑器和廢水處理的流量工業系統應用
特點
壽命周期長，無運動部件磨損或斷裂處理流體中無機械部件的受污染介質的應用
