Abstract
Cette invention se rapporte à un système de détection d'eau, qui sert à détecter la teneur en eau d'un liquide et à communiquer à un opérateur les informations relatives à cette teneur en eau. La communication des informations relatives à la teneur en eau peut comporter le traitement de la valeur de la teneur en eau détectée et la comparaison de cette valeur avec une ou plusieurs valeurs seuils, afin de qualifier la valeur détectée. Selon un autre aspect de cette invention, le capteur d'eau comprend des sorties d'interfaces 4-20 mA isolées à utilser avec des dispositifs extérieurs, tels que des contrôleurs logiques programmables. Selon un troisième aspect cette invention propose un système de détection d'eau qui détecte une valeur de teneur en eau relative et convertit cette valeur de teneur en eau en une valeur de teneur en eau absolue. Selon un quatrième aspect, cette invention utilise des procédés et circuits pour étalonner un système de détection d'eau. Selon un cinquième aspect, cette invention propose un système d'épuration de liquides, qui détecte la teneur en eau d'un liquide et en extrait l'eau à l'aide d'un épurateur.
