W1 Standpipe Piezometer
The W1 Standpipe Piezometer is a reliable and cost-effective Casagrande type piezometer designed for monitoring in vertical boreholes. At Monitel, we have used it to measure groundwater levels and pore water pressures on sites across Western Australia.
The sensor is typically installed with the filter tip positioned at the chosen monitoring depth. For pressure data, the tip is surrounded by sand and enclosed with a bentonite seal to isolate the measurement area. Water level data can be gathered through a riser pipe or a Bourdon gauge (in artesian conditions). The W1 is suitable for various ground types and can be customised to match specific site requirements. It can be deployed with either a porous or ceramic tip and has a drive-in capacity for softer soils. The simplicity, versatility and reliability of the W1 Standpipe Piezometer make it an ideal choice for an accurate and consistent groundwater monitoring solution. Key Specifications:- Available in various lengths up to 3m
- 43mm diameter
- PVC or galvanised steel riser pipe options
- Permeability of 3 x 10-4 m/s
Our team most commonly integrates the W1 into borehole monitoring systems. This is because the sensor is suited to projects where manual measurements are sufficient and long-term real-time data isn’t required.
Once the piezometer is installed, we track groundwater levels to gain insight into aquifer behaviour, pore pressure changes or site drainage conditions. This data is useful for site investigations, construction staging and baseline studies. These piezometers are particularly useful during site investigations, construction staging, or environmental baseline studies where cost-effective, durable monitoring is a priority. Other applications for this sensor include:- Slope Stability Monitoring
- Dewatering and Drainage Control
- Seepage and Groundwater Movement
