Accurate and continuous monitor water level monitoring is demanded in different environments. Piezoelectric sensors are widely used for water level monitoring and work submerged in waters subject to the presence of solid particles, biological fouling and saltwater oxidation. This work aimed to develop a simple low-cost methodology to protect sensors over long-time deploy. The results show that simple actions, costing less than ? 2, can protect and extend the lifecycle of equipment worth over ? 2,000, insuring continuously monitoring and still maintain quality measurements.  ahydrographic  ahydrological  alow-cost protection  amonitoring1 aVANZ, A.1 aBOLL, M.
