Resumen
The article discusses the issue of hydrostatic leveling. Its application is presented in structural health monitoring systems in order to determine vertical displacements of controlled points. Moreover, the article includes a complete computation scheme that utilizes the estimation from observation differences, allowing the elimination of the influence of individual sensors? systematic errors. The authors suggest two concepts of processing the measurement results depending on the sensors? connection method. Additionally, the second concept is extended by the elements allowing the prediction of the displacements by means of Kalman filtering.
