Model 601 Standpipe Piezometer

Model 601 Standpipe Piezometers are composed of a 3/4" diameter PVC body, which is perforated to expose the preformed Vyon filter inside. The PVC tip connects to plain end 3/4" Sch. 40 PVC riser pipe with push-fit couplings. Standpipe Piezometers are available in standard lengths of 6", 1 ft., 2 ft. and 3 ft. (15 cm, 30 cm, 60 cm and 90 cm). The Standpipe Piezometer is primarily used to provide a filtered inlet point when backfilled in place within a pre-drilled hole or test pit. The pointed tip can also be pushed into very loose sands at the base of a borehole, stream, or into loose tailings pond sediments.. Standpipe Piezometers are great for water level monitoring, permeability measurements, slope stability investigation, dewatering operations, air sparging and metals sampling. Standpipe Piezometers are designed for placement within a drilled hole to provide a filtered inlet point. Piezometers can also be manually pushed into suitable sediment, such as very loose sands at the base of a borehole, a stream, or into very loose tailings pond sediments. After the Standpipe Piezometer is installed to depth, groundwater enters through the porous filter and into the riser pipe, allowing water level monitoring, metals sampling, permeability measurements, slope stability tests, etc. The 60-micron filter in the 601 Piezometer is also ideal for air sparging and metals sampling.
