1、巴歇尔槽非满管状态流动的水路称作明渠(open channel)，明渠流量计的应用场所有城市供水引水渠、火电厂冷却水引水和排水渠、污水治理流入和排放渠、工矿企业废水排放以及水利工程和农业灌溉用渠道。我公司专业生产与明渠流量计配套使用的各种规格的量水堰槽（巴歇尔槽）、堰板（三角堰，矩形堰）。用途与明渠流量计 ( WL-1A型超声波明渠流量计) 配合使用，把明渠内流量的大小转成液位的高低。测量明渠内水的流量。如灌渠、污水沟、城市下水道的流量。材质玻璃纤维不饱和聚酯复合材料（玻璃钢）。测量范围流量范围 :10 升/ 秒 10 立方米 / 秒( 由配用巴歇尔槽的规格决定)典型案例为六盘水污水厂生产加工
2、B1800型巴歇尔槽，最大流量达到 10000 立方米 / 小时为青岛麦岛污水处理厂加工B600型巴歇尔槽，流量达到 3300 立方米 / 小时为北京密云环保局、云南文山州环保局、包头市环保局、大连市环保局、天津环保局、武汉环保局、山西运城环保局等下属的一百多家企业提供了各种规格（B51 、B76 、B152 、 B228 、 B250 、B600 、B1500 、 B1800 ）的堰槽、堰板 ( 巴歇尔槽和三角堰、矩形堰).注意事项精品文库巴歇尔槽的中心线要与渠道的中心线重合,使水流进入巴歇尔槽不出现偏流。巴歇尔槽通水后，水的流态要自由流。巴歇尔槽的淹没度要小于规定的临界淹没度。巴歇尔槽的上
3、游应有大于 5 倍渠道宽的平直段，使水流能平稳进入巴歇尔槽。即没有左右偏流，也没有渠道坡降形成的冲力。（参见下图）巴歇尔槽安装在渠道上要牢固。与渠道侧壁、渠底连结要紧密，不能漏水。使水流全部流经巴歇尔槽的计量部位。巴歇尔槽的计量部位是槽内喉道段。巴歇尔槽构造图欢迎下载2精品文库巴歇尔槽构造尺寸（单位：米）类序喉道段收缩段扩散段墙高别号bLNB1L1LaB2L2KD10.0250.0760.0290.1670.356 0.2370.0930.2030.0190.23小20.0510.1140.0430.2140.406 0.27101350.2540.0220.26型30.0760.1520.0
