A gravimeter or gravitometer, is an instrument used in gravimetry for measuring the local gravitational field. A gravimeter is a type of accelerometer, except that gravimeters are susceptible to all vibrations including noise, that cause oscillatory accelerations. This is counteracted by integral vibration isolation and signal processing. Though the essential principle of design is the same as in accelerometers, gravimeters are typically designed to be much more sensitive than accelerometers in… (More on Gravimeter)
