The Model 601 Standpipe Piezometer is designed to provide a filtered inlet point when it is placed within a drilled hole. Its pointed PVC tip makes it ideal for pushing into very loose sands at the base of a borehole, a stream or into loose tailings pond sediments.
It is composed of a pre-formed porous polyethylene tube set inside a perforated PVC Piezometer tip which makes it excellent for metals sampling. It is ideally suited for water level monitoring, de-watering drainage operations, permeability measurements, and construction control and slope stability investigations.
The Standpipe Piezometer tip connects to the surface with 3/4” ID PVC riser pipe using slip-fit couplings. It can also be used to connect to other sizes of riser pipe or casing if reducer couplings are used. The standard 601 tip lengths available are: 15 cm, 30 cm, 60 cm and 90 cm (6”, 1 ft, 2 ft and 3ft).
For applications with a need for the Piezometer to be pushed into the soil below the bottom of a borehole, Solinst offer the Model 615 stainless steel Drive-Point Piezometer. This can also be driven directly into the ground from the surface.
