Standpipe Piezometers

Standpipe Piezometers

Product Description

The Standpipe Piezometer allows levelling and sampling of groundwater and in-situ permeability testing. Upgrading with a diaphragm type piezometer (Model 1100 or Model 1200) is possible at a later stage.
The large number of uniform pores permit high permeability in a short length. In order to obtain the same open area as a 300mm length of plastic filter material, one would require 7m of standard 25mm slotted pipe. Drive-in models available (Model 1050).

Application

• Monitoring of pore pressures in dams and embankments.
• Slope stability investigation.
• Leachate extraction.
• Groundwater sampling and monitoring.
• Dewatering and drainage operations.

Features

• Protected filter element.
• Uniform filter porosity.
• Smooth filter element resists clogging.
• May be cleaned by back flushing.
• Excellent chemical resistance.
• Drive-In models available (galvanised steel).

Specifications

• Permeability: 3 x 10-4 m/s (low air entry).
• Pore diameter: 70 micron.
• Filter area: 245 cm2.
• Dimension (PVC): 33.4 mm x 354 mm long.
• Dimension (galvanised steel): 33.8 mm x 370 mm long.
• Weight (PVC): 0.14 kg.
• Weight (galvanised steel): 1 kg.
