选择合适的多层次系统
对滑铁卢、CMT、水笛和多级驱动点压水计地下水监测系统的比较
深度离散监测的好处早已众所周知。
哪种 Solinst 系统适合您的应用?
滑铁卢系统(自 1984 年起)
滑铁卢系统 它采用模块化设计,具有出色的现场和应用灵活性,可根据井眼测井情况放置端口和封隔器。工程密封件和专用取样及液位监测功能的使用深度可达 1000 英尺(300 米)。它们非常适合在基岩和套管井中进行长期监测。
《水笛》(自1996年起)
405型“水笛”系统采用柔性衬管对钻孔内部进行密封,仅在规定的采样间隔处留有开口。“水笛”完全扩张贴合于钻孔壁面,确保水不发生混合。 根据钻孔直径(4 至 19 英寸以上(10 厘米至 48 厘米))的不同,衬管可设置 15 个或更多监测端口。该系统已安装至 1400 英尺(425 米)的深度。
CMT 系统(自 1999 年起)
CMT 多层次系统 提供现场设计的灵活性、低成本和易于安装。监测端口的数量、端口位置、安装深度和监测策略都可以在现场进行设计。单管可提供有效的密封。7 通道系统为 1.7 英寸(43 毫米),3 通道为 1.1 英寸(28 毫米)。它们是窄直径钻孔浅层应用的理想选择。
多级驱动点压水计(自2021年起)
615ML 多级驱动点压水计配备不锈钢监测口,通过 3/4 英寸 NPT 钢制驱动管和接头连接。 双倒钩阀杆允许连接管路根据管径大小,最多划分出3个或6个监测区。可采用直接推入法(包括滑锤法)进行简便安装,非常适合极浅层应用。

Best For
Very shallow hand-driven investigations and rapid installation. Ideal for soil gas and surface/ groundwater interaction applications.
Low cost, shallow, flexible in-field design. Best for soil gas and groundwater applications in the same borehole. Most popular option.
Deep, long-term bedrock and cased-borehole monitoring with dedicated transducers and pumps.
Works with T-Profiling, NAPL/ FACT Liners for deep boreholes requiring multiple zones and continuous interval isolation that’s removable.
