Abstract
L'invention concerne un appareil doseur mécanique-hydraulique comportant une pompe doseuse pour l'introduction dosée d'agents chimiques dans une conduite d'eau. Un tel appareil doseur comporte un transmetteur de pression différentielle qui établit, entre deux points de la conduite de liquide, une pression différentielle proportionnelle au débit et à la contre pression. Par ailleurs, les côtés de haute et basse pression du transmetteur de pression différentielle sont reliés à une servocommande servant à actionner la pompe doseuse. Utilisation notamment dans les conduites de liquide.
