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.

An inclinometer sensor's true or absolute accuracy (which is the combined total error), however, is a combination of initial sets of sensor zero offset and sensitivity, sensor linearity, hysteresis, repeatability, and the temperature drifts of zero and sensitivity—electronic inclinometers accuracy can typically range from ±0.01–2 ...
Reaction arrows about the output axis (blue) correspond to forces applied about the input axis (green), and vice versa. A gyroscope is an instrument, consisting of a wheel mounted into two or three gimbals providing pivoted supports, for allowing the wheel to rotate about a single axis.
osmotic strength of a solution, colloid, or compound matter of an object parking meter: collects moneys for vehicle parking rights in a zone for a limited time pedometer: steps pH meter: pH (chemical acidity/basicity of a solution) photometer: illuminance or irradiance planometer: area polarimeter: rotation of polarized light potentiometer
Plumb bob with scale as an inclinometer Plumb bob with string in masonry work. A plumb bob and line alone can determine only a vertical reference. However, if they are mounted on a suitable scale the instrument may also be used as an inclinometer to measure angles to the vertical.
Liquid capacitive inclinometers are inclinometers (or clinometers) whose sensing elements are made with a liquid-filled differential capacitor; they sense the local direction of acceleration due to gravity (or movement). [1] A capacitive inclinometer has a disc-like cavity that is partly filled with a dielectric liquid.
The slip indicator is actually an inclinometer that at rest displays the angle of the aircraft's transverse axis with respect to horizontal, and in motion displays this angle as modified by the acceleration of the aircraft. [1] The most commonly used units are degrees per second (deg/s) or minutes per turn (min/tr). [citation needed]
The series of experiments began at the California Institute of Technology in 2002. In collaboration with the Jet Propulsion Laboratory , physicists Andrew Lange , Jamie Bock, Brian Keating , and William Holzapfel began the construction of the BICEP1 telescope which deployed to the Amundsen-Scott South Pole Station in 2005 for a three-season ...
