Comparing Multilevel Systems
 |
 |
The benefits of depth discrete monitoring have been known for years. Which Solinst system will suit your application?
|
 |
|
 |
CMT offers in-field design flexibility, low cost and is easy to install. The number of monitoring ports, port locations, install depths, and monitoring strategy, can all be accommodated and designed right in the field. The single tube offers effective sealing.The 7-Channel is 1.7" (43 mm) and the 3-Channel is 1.1" (28 mm).
Waterloo Systems have a modular design that gives a similar flexibility to application as that of the CMT. Their design is much more suited, however, for deeper installations. The engineered seals and dedicated sampling and level monitoring capabilities have been used to 1000 ft (300 m). They are ideal for use in bedrock and for long term monitoring.
