Webinstallation. Tiltmeters are mounted at the ground surface. They are an option for those sites that are too steep for a drill rig or if the project budget does not allow for drilling. Tiltmeters also can be covered with a vandal-proof enclosure and wires can be buried. Electrolytic bubbles are used in tiltmeters and “in-place” inclinometers. WebTiltmeters measure the amount of tilt in microradians, which is the angle turned by raising one end of a beam one kilometer long the width of a dime (equivalent to 0.00006 degree!). Originally designed as part of the guidance and control system for military missiles, a variety of electronic tiltmeters are now
