金屬管浮子流量計公司解答:電磁流量計真的好用嗎?金屬管浮子流量計公司回答：電磁流量計的丈量原理是根據法拉第電磁感應定律:導電液體在磁場中作切割磁力線運動時，導體中發生感應電勢，其感應電勢E為:E=KBVD 式中:K----外表常數 B----磁感應強度 V----丈量管道截面內的均勻流速 D----丈量管道截面的內徑丈量流量時，導電性液體以速度V流過垂直于活動方向的磁場，導電性液體的活動感應出一個與均勻流速成正比的電壓，其感應電壓信號經過二個或二個以上與液體直接觸摸的電極撿出，并經過電纜送至轉換器經過智能化處置，然后LCD顯現或轉換成標準信號4~20ma和0-1khz輸出。電磁流量計應用領域廣泛。大口徑外表較多應用于給排水工程，中小口徑常用于固液雙相等難測流體或高需求場所，小口徑、微小口徑常用于醫藥工業、食品工業、生物工程等有清潔需求的場所。
