<\/span>uses modular components of various casing lengths, sampling ports, and optional packers that are connected to form a sealed casing string. Pumps and\/or transducers can be dedicated to each port. All instrument tubing and cabling is contained within these modules and collected at the top of the system at a wellhead manifold. The Waterloo System is ideal for long-term monitoring in bedrock and cased boreholes, and has been used to depths of 1000 ft (300 m) (see Model 401 Data Sheet). <\/p>\n[\/et_pb_text][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner column_structure=”1_3,1_3,1_3″ use_custom_gutter=”on” _builder_version=”4.27.4″ _module_preset=”3676f7e6-7b83-4698-94ce-2cc9fa9ae43d” hover_enabled=”0″ global_colors_info=”{}” background__hover_enabled=”on|hover” sticky_enabled=”0″][et_pb_column_inner type=”1_3″ saved_specialty_column_type=”3_4″ _builder_version=”4.27.2″ _module_preset=”default” background_color=”RGBA(255,255,255,0)” custom_padding=”|||0px|false|false” custom_css_free_form=”width: 68%!important;||margin-right: 2%!important;” global_colors_info=”{}” background__hover_enabled=”on|hover” background_color__hover=”” background_enable_color__hover=”off”][et_pb_image src=”https:\/\/www.solinst.com\/wp-content\/uploads\/2025\/01\/615ml-multilevel-drive-point-piezometer.webp” alt=”615ml multilevel drive point piezometer” title_text=”615ML Multilevel Drive Point Piezometer” align=”center” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n
