Piezometer

Innovative series IG-1400/1500 piezometers are used to measure ground water elevations and pore water pressures in bore holes, embankments, concrete structures, pipe- lines, wells, mines, tunnels etc. Model IG-1501 has the filter replaced with a threaded adapter to permit it to be coupled directly to pressure lines. Provision of gas discharge tube protects the sensor against surge and lightning.

Typical Applications

• Controlling water pressure during consolidation by continuous monitoring.
• Prediction of slope failure and remediation.
• Design for lateral earth pressures.
• Design for uplift pressures and buoyancy.
• Monitor seepage, determine phreatic line and verify models of flow.
• Monitor surface water run-off.
• Monitor rate and direction of flow of contaminated water.
• Monitor encroachment of salt water into fresh water acquifiers.

Outstanding features

• Unprecedented sensitivity, long term stability and reliability.
• Isolation of the sensor assembly from the effects of total stresses acting on the body of the piezometer.
• Robust and sturdy construction.
• Slim-line design.
• Corrosion resistant option available for coastal applications.
• Provision of thermistor for temperature measurement.
• Provision of gas discharge tube for lightening and surge protection.
• Suitable for remote reading, scanning and Data logging.
• No effect of cable length on performance of the sensor.
