In recent months, we have carried out an interesting project to install sensors within the Slovak motorway network. Due to the melting of oil separator (ED) tanks during the period of increased precipitation, it is necessary to individually inspect a large number of tanks to see if the filters are clogged and thus overcrowding the tank. To this end, the Granvia Company has chosen a solution from the Sensoneo company, which Hurican Slovakia has implemented in cooperation with the Slovanet company. This is a float system that remotely alerts you when there is an increase in the level in the tank and thus saves the cost of human crew inspection trips to the site. Hurican Slovakia installed this solution on 26 locations on a section of the R1 motorway around the town of Nitra.
