  • Device and method for determining the gas content of a liquid
    Publication number: 20050092062
    Abstract: The invention describes a device for determining the gas content of a liquid. The device has at least a housing, a measuring chamber base with a cavity and a measuring chamber cover inside the housing. The measuring chamber base and the measuring chamber cover are each movable by a respective piston independently of one another along the longitudinal axis of the housing. The measuring chamber base and the measuring chamber cover form a measuring chamber in the housing. The measuring chamber base or the measuring chamber cover is connected to a pressure sensor and the housing has a liquid inlet and a liquid outlet.
