  • Fluid mixture metering device including an arcuate path on the periphery of the impeller wheel
    Patent number: 8707780
    Abstract: The device for metering fluid mixtures, in particular liquids containing a gas such as carbon dioxide, includes a flow sensor, a metering valve, and a controller that drives the metering valve as a function of a set point and of the flow rate measured. The flow sensor has an impeller wheel having a horizontal axis, the fluid mixture being guided on an arcuate path on the periphery of the impeller wheel, the path being directed from bottom to top. Despite the presence of gas, a precise metering is achieved.
