Continuous data logging and real-time monitoring helps to provide early warning in case of impending failure allowing time for corrective action to be taken or if necessary for safe evacuation of the area. Tilt change in a structure may be caused by construction activity like excavation, tunneling or de-watering that may affect the ground supporting the structure. Change in tilt could also result from loading of the structure, such as loading of a dam during impoundment, loading of a diaphragm wall during excavation or loading of a bridge deck due to wind and traffic. Data from the tilt meter provides early warning of threatening deformations, allowing time for corrective action to be taken or if necessary for safe evacuation of the area. 1.1 Applications EAN-95MWtilt meter is widely used in following applications: ▪ Monitoring vertical rotation of retaining walls. ▪ Monitoring inclination and rotation of dams, piers, piles and other structures. ▪ Monitoring stability of structures in landslide areas. ▪ Monitoring tunnels for convergence and other movement. ▪ Monitoring safety of structures around zones of excavation or tunnelling. ▪ Monitoring deflection in bridges and struts under different loading conditions. 1.2 Conventions used in this manual WARNING! Warning messages calls attention to a procedure or practice that if not properly followed, could possibly cause personal injury. CAUTION: Caution messages calls attention to a procedure or practice, that if not properly followed may result in loss of data or damage to equipment. NOTE: Note contains important information and is set off from the regular text to draw the users’ attention. 1.3 How to use this manual This users’ manual is intended to provide you with sufficient information for making optimum use of tilt meters in your applications. To make the manual more useful we invite valuable comments and suggestions regarding any additions or enhancements. We also request to please let us know of any errors that are found while going through the manual. Users’ Manual EAN-95MW Wireless Tilt meter Page | 2 NOTE: Installation personnel must have a background of good installation practices and knowledge of fundamentals of geotechnics. Novices may find it very difficult to carry on installation work. The intricacies involved in installation are such that even if a single essential but apparently minor requirement is ignored or overlooked, the most reliable of instruments will be rendered useless. A lot of effort has been made in preparing this instruction manual. However best of instruction manuals cannot provide for each and every condition in field that may affect performance of the sensor. Also, blindly following the instruction manual will not guarantee success. Sometimes, depending upon field conditions, installation personnel will have to consciously depart from written text and use their knowledge and common sense to find solution to a particular problem. Installation of a tilt meter requires expertise. It is recommended that potential users themselves practice all the operations laid down in this manual by repeated installations. NOTE: The sensor is normally used to monitor site conditions and will record even a minor change that may affect behaviour of structure being monitored. Some of these factors amongst others, are, seasonal weather changes, temperature, rain, barometric pressure, nearby landslides, earthquakes, traffic, construction activity around site including blasting, tides near sea coasts, fill levels, excavation, sequence of construction and changes in personnel etc. These factors must always be observed and recorded as they help in correlating data later on and also may give an early warning of potential da…
