Such inclinometers are, for instance, used for monitoring volcanoes, or for measuring the depth and rate of landslide movement. Measuring movements in walls or the ground in civil engineering projects. Determining the dip of beds or strata, or the slope of an embankment or cutting; a kind of plumb level. Some automotive safety systems.
Volcano and Earth movement monitoring then used the water-tube, long baseline tiltmeter. [2] In 1919, the physicist, Albert A. Michelson , noted that the most favorable arrangement to obtain high sensitivity and immunity from temperature perturbations is to use the equipotential surface defined by water in a buried half-filled water pipe.

The tilt-angle equals the material friction of the discontinuity wall plus the roughness i-angle (tilt-angle = φ wall material + i) if no real cohesion is present (i.e. no cementing or gluing material between the two blocks), no infill material is present, the asperities do not break, and the walls of the discontinuity are completely fitting at the start of the test, while if the walls of the ...

With the help of these meters, either the gravity values at different locations are measured or the values of Earth's magnetic field are measured. Then these measured values are corrected for various corrections and an anomaly map is prepared. By analyzing these anomaly maps one can get an idea about the structure of rock formations in that area.
The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils.
Second, the various monitoring zones can be developed using standard well development equipment and procedures before the multilevel monitoring systems are installed in the wells. Finally, installing multilevel systems inside multi-screened wells may simplify the task of decommissioning the wells once they are no longer needed.
Sherborne Sensors is a designer and manufacturer of precision inclinometers, accelerometers and load cells. Technologies utilized include mechanical servo , solid state and strain gauge . These precision measurement tools are available as both off-the-shelf and bespoke for use in military, aerospace, civil and industrial engineering applications.
