SF2系列視窗流量計(jì)結(jié)合了可視流量和繼電器或脈沖輸出的功能為一體。黃銅整體結(jié)構(gòu),組合在一起的轉(zhuǎn)輪和陶瓷軸可使該產(chǎn)品在禁受高溫,高壓和化學(xué)腐蝕。如需流量開關(guān)設(shè)定請(qǐng)選擇帶單刀雙擲繼電器輸出的SF2-1儀表,該儀表能夠在選定的流量范圍調(diào)整設(shè)定值,動(dòng)態(tài)轉(zhuǎn)輪能夠防止堵塞和故障。如要進(jìn)行流量監(jiān)視或計(jì)量,請(qǐng)選擇能輸出與流速成比例的脈沖輸出的SF2-2儀表。4.5-24VDC脈沖輸出可與絕大部分?jǐn)?shù)字儀表配合。
