Piezometers

Geonors electrical piezometers are based on the vibrating wire principle. More than 50 years of experience have shown stability on a long term basis. They can be supplied either for push-in penetration in soft or loose soils or for immersion/burial.

When using armoured cable (FERE), the sensor will be marked with an "A" behind the version name, thus “M-610A“ is designed for FERE cable and “M-605” is designed for standard cable.

The  M-610A piezometer can additionally be equipped with temperature sensor.  

M-605 series of "push-in"

• New simplified robust design
• Designed for push in with 1” water pipe.
• For direct push-in penetration use without pre-drilling.

• Quick installation in soft and loose soils.
• Short response time.
• Accuracy better than ± 0.5% FS.
• Pressure range 2 to 10 bar.

M-610A series "embedment"

• Designed for direct mounting.
• Suitable for use in dams, landfills, environmental wells or similar.
• Housing of stainless steel, other materials such as titanium are available on request.
• Measuring range 2 to 30 bar.  

M-207 hydraulic piezometer

The M-207 hydraulic piezometer can be pressed down without pre-drilling, normally until approximately 30 m depth. Intended for Ø32 mm extension tube. Adapted to 1" water pipe.

• Easy to install.
• Simple and robust design.

• For measurement of groundwater level and pore pressure.
• Push-inn penetration without pre-drilling.
• Supplied with bronze filter.
• Read by using a specially designed water-level gauge.

Cable

Geonor supplies cables, specifically designed for geotechnical purposes. The cables are available in two versions. Cable glands and extension sets are available for both types of cables.

Armored special cable 2-pairs FERE

P-430 is a steel reinforced 2-pair cable. It is specially designed to withstand high loads in terms of tension and compression and is protected against water ingress, in case of damaged jacket.

Geonor standard cable

Standard 1-pair standard. Standard version is 1-pair cable with shield and intended for use where the cable is not exposed to large mechanical stresses.
