abstract = {{The Hydrostatic Leveling System (HLS) is commonly employed in Structural Health Monitoring (SHM) to anticipate issues in large-scale structures. Particularly in structures like particle accelerators, it is used in high-precision alignment, where small differences in elevation such as terrestrial tides, could affect machine operation. This study outlines the development and evaluation of the first HLS based in Linear Variable Differential Transformer (LVDT) and were used to monitor the structure at LNLS/CNPEM, Brazil, from 2020 to 2023. A comparative analysis with a capacitance-based off-the-shelf HLS was executed, and experimental data analyzed through Fast Fourier Transform (FFT) confirmed the presence of tidal components in both HLS¿s data. Additionally, the correlation between level and temperature data was demonstrated by Pearson coefficient. The Setup-HLS device, developed with support from Brazilian national resources, exhibited accurate measurements in building tilt and diurnal and semi-diurnal Earth tide variations. Future researches include a calibration jig and an online verification system. This research provides a viable alternative to existing HLS systems.}},
