Installation for measurement of flow-rate in a liquid or fuel distribution system, e.g. a petrol station pump, has a rotor assembly in conjunction with a Hall effect sensor that determines the rotation speed and hence the flow-rate

Installation has a flowmeter placed in the channel where the fluid flows with a rotor (16) and a measurement assembly (10) forming the body of the flowmeter. A Hall effect sensor (20) installed adjacent to the rotor detects the change in magnetic field caused by cavities (24) present in the rotor. T...

More Information
Summary:Installation has a flowmeter placed in the channel where the fluid flows with a rotor (16) and a measurement assembly (10) forming the body of the flowmeter. A Hall effect sensor (20) installed adjacent to the rotor detects the change in magnetic field caused by cavities (24) present in the rotor. The Hall effect sensor is used to determine the rotor rotation speed and hence the liquid flow-rate. An Independent claim is made for an installation for liquid distribution using the above flow-rate determination installation. Installation de mesure,comprenant un débitmètre monté dans un passage de liquide du système de distribution et comportant un rotor (16) et un ensemble de saisie (10) faisant corps avec le débitmètre et comprenant- un capteur à effet Hall (20) installé au voisinage du rotor (16) et coopérant avec celui-ci. Le rotor (16) comporte une cavité (24) présentant des caractéristiques magnétiques pour le capteur pendant la rotation du rotor (16) et un processeur donnant la mesure du débit de liquide Hall.
