Monitoring Options for CMT Multilevel Systems

The narrow, laser marked cable Model 102 Water Level Meter and 102M Mini Water Level Meter with a 4 mm (0.157″) diameter P4 Probe can be used to monitor water levels in any CMT channel. It is narrow enough to be used along side a pump in the same channel.

The Tag Line is ideal to aid accurate placement of sand and bentonite during borehole completion.

The durable cable is laser marked every 1/4 foot or 5 cm.

Ideal for sample retrieval from shallow water levels less than 9m (30 ft.).

Sampling can be performed using the Solinst Peristaltic Pump, which has a suction lift limit of approximately 7.5 m (25 ft). The Mini Inertial Pump can be used with inexpensive polyethylene tubing to depths of 15 m (50 ft), or using PTFE tubing to depths of 45 m (150 ft).

The Micro Double Valve Pump (DVP) is ideal for low flow VOC sampling in narrow applications. The Micro DVP is made of flexible PFAS-free PTFE or polyethylene tubing which is 3/8″ (9.5 mm) in diameter. A manifold at the surface has a quick-connect fitting for attachment to the Solinst Electronic Control Unit and a bypass for easy sample collection. Operation is easy, as the Electronic Control Unit has built in pre-sets.

A multi-purge manifold is also available for the Micro DVP, for depths up to 73 m (240 ft).

Durable and easy to operate with the 408M by using built-in presets, or customized saved settings.

Channel seal assemblies are availabe to seal the CMT channels in case of flowing artesian conditions, or vapor monitoring. If desired, a 3-way valve can be attached to the seal assembly directing vapor to a pressure gauge connected at one end of the valve and a sample vessel at the other.
