主要技術指標
1.無可動部件，運行可靠，性能較好，使用壽命長。
2.測量被測流體，不直接接觸傳感器，性能穩定。
3.輸出信號是與流量成正比的脈沖信號或輸出4~20mA標準電流信號。
4.壓力損失較少，故比差壓流量計具有節能特點。
5.測量量程比大，可達1：10。而差壓式只有1：3。
6.結構簡單而牢固，安裝方便，維修費用極少。
本系列本安防爆型產品經******級儀器儀表防爆安全監督檢驗站(NEPSI)檢驗認可，符合******標準GB3896.1/4-83的規定，其防爆標志為ExibⅡCT1-6，防爆合格證為CXB00285。本產品與關聯設備-安全柵配合使用構成本安全防爆系統后，可應用于相應爆炸性危險場所。用戶在現場安裝使用，須注意下列事項：
產品外殼設有接地端子，用戶在使用產品時，須可靠接地；
本安型渦街流量傳感器須***與經防爆檢驗機構認定的安全柵配接才能構成本安防爆系統；
傳感器與安全柵本安端之間的連接電纜為三芯屏蔽電纜(電纜須***有絕緣護套)芯線截面0.5mm2。其屏蔽層在安全場所單端接地，其電纜布線盡可能排除電磁干擾的影響并使電纜分布參數控制在0.05F之內；
