非滿管狀態流動的水路稱作明渠(openchannel),明渠流量計的應用場所有城市供水引水渠、火電廠冷卻水引水和排水渠、污水治理流入和排放渠、工礦企業廢水排放以及水利工程和農業灌溉用渠道

??非滿管狀態流動的水路稱作明渠(open channel),明渠流量計的應用場所有城市供水引水渠、火電廠冷卻水引水和排水渠、污水治理流入和排放渠、工礦企業廢水排放以及水利工程和農業灌溉用渠道。我公司專業生產與明渠流量計配套使用的各種規格的量水堰槽(巴歇爾槽)、堰板(三角堰,矩形堰)。

用途

??與明渠流量計(WL-1A 型超聲波明渠流量計)配合使用,把明渠內流量的大小轉成液位的高低。測量明渠內水的流量。如灌渠、污水溝、城市下水道的流量。

材質

??玻璃纖維不飽和聚酯復合材料(玻璃鋼)。

測量范圍

流量范圍:10升/秒~10立方米/秒(由配用巴歇爾槽的規格決定)
