Main features
HLS (Hydrostatic Levelling System) and WPS (Wire Positioning System) are metrology systems used for controlling and monitoring deflection and drift of large buildings and infrastructure. They offer high-precision metrology during construction, operation and maintenance of the structure, even in harsh environments. This solution is field-proven on various infrastructures: synchrotron, bridge, dams, nuclear plant, telescope …
HLS and WPS sensors are networked along the infrastructure or site, and connected to power and data acquisition racks (RIA) that allow continuous data acquisition through a PC system. An optional Multi-system Software Measurement (MSM) allows to check the sensor status and measurement.
Key benefits
Predictive monitoring: The metrology sensors’ high sensitivity and real-time operation ensures detection of all environmental events: earthquakes, tides, seasonal temperature changes, ground water level, ground level fluctuations, structure loading, construction environment … This allows to identify critical events and make optimised decision to carry-out the necessary safety procedures or maintenance work.
Lifetime supervision: The metrology system is designed to be installed and operate on the structure during a long time. It can also replace laser-based systems for regular checks or short-term controls during construction and maintenance.
Large area monitoring: the networked architecture allows the system to be implemented within areas of several hundred meters or even larger.
Environment resistance: The sensor design is not sensitive to environmental conditions that often affects laser-based systems. These can be used in high radiation environments like nuclear power plants or particle accelerators.
Very high accuracy: Micrometer-range accuracy makes the solution suitable for the control of highly sensitive structures like synchrotrons and large telescopes.

HLS – Hydrostatic Levelling System
- Measurement range: 20-100mm or custom
- Repeatability: 0.5-300 micron
WPS – Wire Positioning System
- Measurement range: 2.5-20mm or custom
- Repeatability: 1-10 micron
RIA – Power & data acquisition rack
- Multi-sensor compatibility
- 16 measurement channels
- Continuous data acquisition
HLS and WPS engineering instrumentation systems makes use of high performance capacitive sensors.
HLS Hydrostatic Levelling System sensors are based on the principle of communicating vessels, with a liquid reservoir as a unique altimetry reference for all the sensors of the system. This allows to take levelling measurements within several hundred meters with an unmatched accuracy.

WPS Wire Positioning System uses a tightened wire as a measuring reference. It measures the wire position in 1 or 2 axis with regard to fixed reference planes within the sensor.
