  • Patent number: 10094693
    Abstract: A flow meter includes a housing which accommodates helical guide blades and a core located within the guide blades, and a measuring chamber in which a measuring ball can rotate in a circle. Between the end of the core bounding on the measuring chamber and the end face of the outlet section oriented to the measuring chamber there are no wall portions present, and the distance between the outside edge of the core end bounding on the measuring chamber and the inside edge of outlet-section-end-face oriented to the measuring chamber is smaller than the diameter of the measuring ball. Consequently, the fluid may unimpedely flow out of the measuring chamber as a result of which there is low flow resistance of the flow meter. Moreover, this causes no obstacles to be present between two oppositely arranged spots on the housing that may disturb a light ray for the measurement.

  • Patent number: 10082486
    Abstract: A method for recognizing the presence of liquid (30) in a gas flow flowing in a pipeline uses an ultrasound flowmeter (10). Measurement paths are provided in pairs which are displaced vertically by an equal predefined distance with respect to the center axis such that one lies in an upper region above the center axis and one lies beneath the center axis. A check is made in three stages to define various measurement values, turbulence values and speed of sound values. A liquid warning signal is output when an invalid measurement value is delivered in the first stage, or when the ratio of the turbulence values in the second stage differs from 1 by more than a predefined tolerance value, or when the ratio of the speeds of sound in the third stage differs from 1 by more than a predefined tolerance ratio.
