For a typical installation, Canary Systems will first gather the zero reading of each piezometer. Once the truck is positioned next to the drill hole, the deepest piezometer is taped to a ½” fiberglass rod. Utilizing the fiberglass rod allows for installation of sensors in any orientation. The rod is pushed down the hole using a dual hydraulic motor tractor belt drive and additional piezometers are added at predetermined distances from the other instruments for a nested installation. Depending on the standard hole size and final installation depth, between 1 and 8 sensors may be installed at once. The maximum hole depth is 5000’ (1500m).

One of the most innovative features of the truck is the guide arm system for the fiberglass rod. The guide arm is designed to maintain full control of the fiberglass rod as it enters the hole, eliminating the need for any attachments to the drill rig and potential breakage of the rod. The piezometers are also fed along the guide arm and meet up with the rod at the top of the hole for a seamless transition entering the casing and keeping aligned through the process for accurate instrument placement.

Overall the installation reel truck permits for more consistent and efficient installations of piezometers with the mounted guide arm providing for a safer and more controlled feed of the fiberglass rod and instrument cables into the hole.
