Abstract
La presente invenzione, applicabile nel settore degli impianti idrici in genere, è un dispositivo idoneo al costante controllo in automatico della presenza di acqua all'interno di una qualsiasi rete di distribuzione idrica civile od industriale. La caratteristica del trovato sta nel fatto di interrompere all'istante il flusso elettrico alla pompa dell'impianto idrico preposta alla distribuzione dell'acqua, impedendone il funzionamento a vuoto quando non vi sia presenza di acqua e viceversa ristabilire il flusso elettrico, quindi il razionamento della pompa, quando vi sia di nuovo presenza di acqua.Lo scopo del trovato è pertanto quello di dare affidabilità, semplicità di installazione e massima garanzia di continuo funzionamento ai vari organi che compongono un impianto idrico in genere, annullando qualsiasi tipo di problematica oggi presente, riducendone al massimo la manutenzione.
