Slope indicators are pieces of equipment applied in the measurement of angles of slope, depression, or elevation on an item with regard to the pull of gravity. Slope indicator is also known by several other names including tilt meter, level gauge, level meter, slope gauge, declinometer, gradiometer, and gradient meter among many others. There are many different types of this device in use today.
Both positive and negative tilt can be measured by inclinometers. In positive slopes observers look at objects upwards while in negative tilt, the look downward. Degree, topo, and percent are the three primary units of measurement used in tilt meters. During Renaissance period, the kind of inclinometers that were used are called astrolabes.
The Renaissance period saw astrolabes being used widely. Their use was in navigation and location of astronomical objects. Astrolabes declined in use as technology advanced and better devices started being developed. Current tilt meters are highly functional and very developed. Sometimes turn coordinators incorporated in aircrafts are called tilt meters.
Application of technology in these devices has led to achievement of high levels of accuracy. Modern electronic level meters have sensors that allow them to reach an output resolution of up to 0.0001 degrees. The accuracy is dependent on such factors as angle range and technology used. Some lower level technologies can only achieve accuracies of 0.01 degrees. Absolute accuracy of sensors is usually a result of a combination of factors including hysteresis, sensor linearity, repeatability, zero offset, sensitivity, and temperature.
There is a lot of variance in the accuracy of electronic level meters. The variance is often dependent on the situation and the model of the device in use. The range within which accuracy usually falls is 0.01 degrees to negative or positive two degrees. Accuracy remains within the linearity specifications of a sensor under room ambient conditions.
There are many applications in which level gauges find use. Typically, they are used by engineering in the monitoring of subsurface deformations and movements. They come in handy in detecting zones of movement for the purpose of establishing consistency or acceleration in movement. During and after impoundments, the gadgets verify upstream slopes, dam abutments, and stability of dams.
Two basic components are found on modern inclinometers, the inclinometer measurement system and the inclinometer casing. Access for subsurface measurements is provided by the inclinometer casing. Casings have grooves for controlling orientation of the sensor on devices and offering a uniform surface for measurements to be taken. Casings may be embedded in fill, installed in boreholes, cast into concrete, buried in trenches, or attached to structures.
There are two types of inclinometers, that is, portable measurement systems and in-place measurement systems. Like suggested in the names, the former can be carried from place to place to take measurements while the latter is usually installed permanently in a place. In-place measurement systems are needed when there is need for continuous monitoring for safety or construction control.
