流量和總計輸出
SFI-100T系列可視流量指示器和變送器是一種低成本、耐用的流量變送器，它將我們流行的100系列可視流量指示器與我們的a-711T輸出傳感器結(jié)合起來，用于可視和遠程監(jiān)測流量。A-711T輸出傳感器有兩個脈沖電壓信號，一個提供5 VDC脈沖，另一個提供所用輸入電源電壓的脈沖，范圍為8至28 VDC，脈沖輸出的頻率變化與流速成比例。
產(chǎn)品應用
監(jiān)控冷水或熱水流量監(jiān)控冷水機冷卻和潤滑回路中的水流量hvac系統(tǒng)
特征
由堅固的黃銅主體和鋼化玻璃窗構(gòu)成
鮮紅的葉輪能清楚地顯示出通過窗戶的水流
前車窗可以很容易地擰下，以清除可視流量指示器
戶外應用的理想選擇，不受紫外線影響
