VWPHT-3600 SERIES
The VWPHT-3600 series High Temperature Piezometers are suitable for the extreme environments of temperature and pressure found within applications such as geothermal heat and enhanced oil recovery systems including steam assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS). They are capable of monitoring high temperatures up to 250°C and pressures up to 34.5 MPa.
Description
They use the well-proven vibrating wire technology of converting fluid pressures onto a pressure sensitive diaphragm which when deflected causes a change in tension and the corresponding change of frequency of the wire. In addition, an internal high temperature thermistor allows the temperature at the piezometer location to be measured.
Manufactured from high temperature and corrosion-resistant materials throughout, together with a comprehensive temperature calibration, they provide high accuracy stable long-term data with no zero shift.
The specially-designed Tubular Encapsulated Cable (TEC) is both high temperature resistant and highly flexible for easy installation within boreholes or above ground.
Also available as a pressure transducer with a threaded connection in the base.

Drive-in piezometers, also referred to as push-in piezometers, are designed for installing in soft clays, organic or fine grained cohesionless soils typically with a SPT-N value less than 10. They are available with a CPT fitting or 1” BSP thread.
Depending on the depth and type of soil, they can either be pushed directly into the soil from ground level to the required depth or pushed into the base of a CPT test or drilled borehole.

The Nano range uses the same core platform as our other tilt sensors, so it can deliver a similar level of performance and reliability, all in a small and robust enclosure. Nanos have been successfully used in many applications, including:
- Tunnel distortion
- Tunnel heave/settlement
- Embankment slippage (used in conjunction with stake mounts)
- Structural movement
- Rail track heave/settlement
- Rail trackbed cant and twist
