Geosense® 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:
| Pressure Range | 70 kPa to 20 MPa |
| Over Range | 1.5 x rated pressure |
| Resolution | 0.025% FS |
| Accuracy | ± 0.1% FS |
| Non Linearity | <0.5% FS |
| Calibrated Temperature Range | -20 to +80°C |
| Frequency Range | 1850 to 3500 Hz |
Whether you require monitoring or testing instrumentation, rentals or service, we are where you need us to be across Canada.
