Page 5: Waterloo Multilevel System Pre-Installation Requirements
*Note: Boreholes must be stable, circular, smooth and straight for best packer seal. Using the layout of monitoring equipment at the proposed depth, Solinst can assist the client in determining the appropriate number of components to achieve your proposed monitoring scenario for the Waterloo Multilevel System. -
Page 6: Introduction
Waterloo Multilevel System Assembly Manual 1.0 Introduction The Waterloo Multilevel Monitoring System is comprised of modular units designed to allow discrete monitoring from several zones within a single borehole. A variety of portable and dedicated instrumentation allows users to retrieve samples, determine piezometric head, temperatures, and conduct basic hydraulic conductivity tests at each zone. -
Page 7: Installation Components
Waterloo Multilevel System Assembly Manual 2.0 Installation Components Individual components of the Waterloo Multilevel System include: PVC Casing, stainless steel Base Plug or PVC Base Plug, stainless steel Ports (single and dual stem), Permanent Packers, and Wellhead Manifolds. Components are shown in Figure 2-1. -

Waterloo Multilevel System Assembly Manual Be sure there is a clean cut to the tubing end at the Port. Place one single ear Oetiker #14 clamp over the tubing and push the tubing end onto the stainless steel Port Stem. Using the Oetiker pliers, squeeze the clamp ‘shoulders’ together to securely attach the tubing to the stem. - Page 16 Waterloo Multilevel System Assembly Manual Each one of the VWT’s cables has been cut to the length requested in the original NOTE order. This length also includes an additional 10% contingency. The total cable length is labeled on the cable’s end. Match the serial number on the body of the VWT with the label at the end of the cable.
