Generally hydrostatic levellings are used for the determination of settlements as well as accelerometers or inclinometers for the inclination measuring in the structural monitoring. Previous hose levelling measuring instruments are mechanical, electrical, magnetic or mostly automated. All mechanically moved components in the traditional instruments for settlements and inclinations are exposed to particularly heavy wear and they have to be repaired extensively. Due to the development of the hydrostatic, optical electronic laser precision hose levelling instrument (LSW), it‘s possible to combine the two tasks of measuring settlement and inclination in one highly accurate instrument. With the new LSW, changes in settlements, inclinations, temperatures can be determined automatically in real-time at discrete intervals for example of 1 sec, 10 sec or 6 hours. The relative differences in height (settlements) were determined with a standard deviation of 0.1 mm to 0.2 mm in the vertical measuring range of approx. 200 mm.
