STANDPIPE PIEZOMETER
Simple and economic measurement of groundwater pressures in soil and rock can be carried out using Casagrande type (standpipe) piezometers.
Description
Geosense® Casagrande piezometers are made up of low air entry porous plastic or ceramic elements which are connected to standpipe tubing and lowered into a predrilled borehole. Alternative types may be driven or pushed into soft soil.
Where Casagrande type piezometers are being installed then the porous element is surrounded by filter sand and a Bentonite seal placed above this response zone.
Water level measurements are normally taken using a water level meter (dip meter) or in the case of artesian pressure a Bourdon pressure gauge is attached to the top.

BOREHOLE ROD EXTENSOMETER
In stock
The Geosense® GEO-XB2 borehole rod type extensometer range is used to measure and locate settlement, displacement and deformation in soil and rock.
It consists of a reference head and one or more in-hole anchors each of which is placed at a known depth and connected to the reference head by either a rigid or flexible rod running inside a flexible sleeve, which keeps the rod de-bonded from the grout.
STRAIN GAUGE PIEZOMETER SGP-3400 SERIES
In stock
The SGP-3400 Series of strain gauge piezometers are designed for monitoring soil pore pressure or changes in water level and are also suitable for dynamic monitoring such as pumping tests.
They are accurate, highly-reliable and suitable for use in the harsh environments often found within civil engineering including water wells, boreholes, dams, reservoirs, rivers, tanks or any other body of water.
DRIVE-IN PIEZOMETERS WP-3400 & SGP-3500 SERIES
In stock
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.
PRESSURE TRANSDUCER VWT-9000 SERIES
In stock
The Geosense® VWT-9000 Series of Pressure Transducers are designed to be connected directly into hydraulic or pneumatic pressure lines by means of a 1/4” BSPF thread. Other thread sizes are available on request.
They are typically used to monitor uplift pressures within dams and to enable manual standpipe piezometers to be upgraded into an automated data acquisition system.
NANO TRIAXIAL TILT SENSOR
In stock
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

PENDULUM SYSTEM
In stock
HPS-3500 (Hanging) and IPS-3000 (Inverted) Pendulums are used to measure the tilt or rotation by measuring the relative internal horizontal displacement of points along a true vertical line. Each has a tensioned, stainless steel wire and the effects of the earth gravitational forces to guarantee a perfectly vertical line between a fixed point and a tensioning mechanism. Typical applications include concrete dams, bridges and high rise buildings.
