Reliable Piezometers for Field Monitoring
piezometer
When projects involve soil stability, dam safety or groundwater control, changes in pore water pressure are often a precursor to risk. Piezometers are sensors designed to capture these subtle water pressure fluctuations. Kingmach has many years of experience In geotechnical instruments. The piezometers we provide cover different principles such as vibrating wire type and pneumatic type, meeting the needs from long-term dam monitoring to short-term foundation pit dewatering. The product line is broad enough and can be customized according to project-specific parameters, which eliminates many compromises when designing monitoring solutions. If you are looking for the right piezometer for a certain project, why not take a look below at our core features and practical applications.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Kingmach's piezometers are designed with field practicality and data reliability in mind. For example, our vibrating wire piezometer has a stainless steel structure as the sensor body. Corrosion resistance is a practical consideration in long-term underground burial. The signal output is stable and the transmission distance is long, making it suitable for large-scale distributed monitoring. For different drilling conditions, the diameter can be customized, ranging from standard 25mm to smaller sizes. The range selection is flexible, with regular models covering 50kPa to 5MPa, and the high-pressure version can also be adjusted according to needs. In terms of installation methods, we can provide push-in, drilled and embedded or embedded directly in concrete, which reduces the trouble of on-site adaptation. From dam seepage monitoring to subway foundation pit precipitation control, Kingmach's piezometers have been on site in many projects. Our technical team can assist with selection, and can also provide calibration and troubleshooting in the later stage - after all, there is a small problem with the sensor in the field, and quick response is more important than anything else. If you need a complete monitoring solution, we can also provide it together with a data collection system, saving you the trouble of piecing it together yourself.

Common technical questions
What is a piezometer and what is it mainly used to measure?
A piezometer is a sensor that measures pore water pressure (or groundwater level). In geotechnical engineering, it is used to understand the distribution and changes of water pressure in soil or rocks, and to help determine slope stability, dam seepage, foundation pit dewatering effects, etc.
How to choose between vibrating wire and pneumatic piezometers?
The vibrating wire type has good long-term stability, is suitable for long-term automated monitoring, and has a long transmission distance. The pneumatic type is sensitive and suitable for scenarios that require real-time feedback, but is affected by changes in air pressure and requires compensation. Which one to choose depends on the project monitoring duration, accuracy requirements and budget. Our team can give you some suggestions.
Can Kingmach's piezometers be customized?
Yes. We can adjust parameters such as diameter, range, cable length, and protection level according to project requirements. If your hole size is special or the medium is highly corrosive, communicate in advance and we can come up with a plan.
What should you pay attention to when installing the piezometer?
The key is to ensure good hydraulic contact between the sensor and the surrounding soil to avoid air bubble blockage. Use permeable material to backfill the borehole to ensure accurate measurement point location. We provide installation guidance and can provide on-site support if necessary.
Do you provide data collection and analysis services?
We mainly provide sensors and supporting collection equipment, and the software can also do basic real-time display and reports. More complex analysis may require your geotechnical engineer to combine it with the geological model. But we will ensure that the data is accurately uploaded.
