VW PIEZOMETER VWP-3000 SERIES
The VWP-3000 Series of Vibrating Wire piezometers use the well-proven method of converting fluid pressures on a sensitive diaphragm into a frequency signal.
FEATURES
- Reliable long-term performance
- Rugged, suitable for demanding environments
- High accuracy
- Insensitive to long cable lengths
Description
The VWP-3000 Series of Vibrating Wire piezometers use the well-proven method of converting fluid pressures on a sensitive diaphragm into a frequency signal.
Frequency signals are particularly suitable for the demanding environment of Civil Engineering applications, since the signals are capable of long transmission distances without degradation, tolerant of wet wiring conditions and resistant to external electrical noise.
Key applications include measuring pore pressure in soils and rocks and fluid pressures in hydro-fractures and pump tests.
Models in the VWP-3000 range are:
- VWP-3000 (STANDARD) Standard construction with high & low air entry filters to measure groundwater elevations and pore pressures.
- VWP-3310 (STANDARD VENTED) Standard construction but vented to compensate for barometric pressure changes. Available with high & low air entry filters.
- VWP-3100 (HEAVY DUTY) Heavy duty body for direct burial in fills and dam embankments. Available with high & low air entry filters, standard and heavy duty cable.
- VWP-3200 (LOW PRESSURE) Low pressure version to measure groundwater elevations and pore pressures. Available with high & low air entry filters.
- VWP-3300 (LOW PRESSURE VENTED) Low pressure vented version to compensate for barometric pressure changes. Available with high & low air entry filters.
- VWP-3400 (DRIVE-IN) Drive-in version available for use with SPT rods.
- VWP-3401 (DRIVE-IN) Drive-in version available for use with 1” BSP adaptor.
