Product Features

• Designed to measure fluid pressures such as ground water elevations and pore pressures when buried directly in embankments, fills, etc.
• Also for installation inside boreholes, observation wells and standard (>19 mm diameter) piezometer riser pipe.
• The Model 4500SH is designed with a heavy duty housing for pressures that exceed 3 MPa.
• The Model 4500AL is designed for low-pressure ranges.
• The vented version (ALV) provides automatic compensation for barometric pressure changes.
• Thermistors are included to measure temperatures.

FOR THE MEASUREMENT OF:

• Ground water elevations
• Pore water pressures
• Pump tests
• Uplift pressures in dam foundations
• Hydraulic pressures in tanks and pipelines
• Wick drain efficiency
• Water pressures behind tunnel linings
