 FT - SW2 雨(yu)量水(shui)(shui)位系(xi)統因為能同時測量雨(yu)量和(he)水(shui)(shui)位而變得實用。FT - SW2 的雨(yu)量測量部分采用翻斗式(shi)結構或光學(xue)雨(yu)量傳感器。它使用雷(lei)達(da)測距原(yuan)理，可適應(ying)不同水(shui)(shui)體環境，實現(xian)遠距離、無接觸式(shi)的精準(zhun)水(shui)(shui)位監測。實時數(shu)據傳輸，能將雨(yu)量水(shui)(shui)位信息及(ji)時發送(song)到監控平臺，方便相關人員遠程查看與分析。一體化(hua)設(she)計便于安裝部署(shu)，廣泛應(ying)用于江河、湖泊、潮(chao)汐、水(shui)(shui)庫閘口(kou)、地下水(shui)(shui)管網、灌渠灌道等場所。

它通過非接觸式測(ce)(ce)量(liang)，結合斷面(mian)參數計算流量(liang)，測(ce)(ce)量(liang)過程(cheng)不受(shou)風、溫(wen)度(du)、霧霾、泥沙、漂浮物(wu)等外(wai)界因(yin)素影響，也(ye)不受(shou)腐(fu)蝕、泡沫干(gan)擾，能(neng)夠穩定(ding)輸出水(shui)位(wei)、降雨量(liang)的(de)測(ce)(ce)量(liang)數據。其(qi)水(shui)位(wei)采(cai)用(yong)(yong)平面(mian)陣列雷達天線(xian)，自(zi)帶測(ce)(ce)量(liang)角度(du)功能(neng)，設備體積小(xiao)巧，安裝便捷。搭(da)配方(fang)便的(de)配置(zhi)軟件，可以(yi)根據實際(ji)需要對(dui)參數進行方(fang)便的(de)配置(zhi)，以(yi)適應不同的(de)使用(yong)(yong)條(tiao)件，且不受(shou)大(da)氣(qi)中水(shui)蒸氣(qi)、溫(wen)度(du)和壓力(li)變化的(de)影響。
