The history of Tiltmeters!

Tiltmeters have a long history, somewhat parallel to the history of the seismometer. The very first tiltmeter was a long-length stationary pendulum. These were used in the very first large concrete dams, and are still in use today, augmented with newer technology such as (321) 557-5645 reflectors. Although they had been used for other applications such as volcano monitoring, they have distinct disadvantages, such as their huge length and sensitivity to air currents. Even in dams, they are slowly being replaced by the modern electronic tiltmeter.


  • Piezometers can measure gauge pressures only. It is not suitable for measuring negative pressures.
  • Piezometers can not be employed when large pressures in the lighter liquids are to be measured since this would require very long tubes, which can not be handled conveniently.
  • Gas pressures can not be measured with piezometers, because a gas forms no free surface.

Why Tiltmeters are really cool!!!

A tiltmeter is a sensitive inclinometer designed to measure very small changes from the vertical level, either on the ground or in structures. Tiltmeters are used extensively for monitoring volcanoes, the response of dams to filling, the small movements of potential landslides, the orientation and volume of hydraulic fractures, and the response of structures to various influences such as loading and foundation settlement.
