Abstract: A method for determining a gas phase mass fraction or mass flow rate of a multi-phase medium flowing in a measuring tube, which includes a break-away edge exposed to the flow and three pressure taps, each influenced differently by the break-away edge, the method including: determining a first pressure drop between the first and second pressure taps; determining a second pressure drop between the third pressure tap and one of the first or second pressure taps; and determining the mass fraction or mass flow rate of the gas phase from the first and second pressure drops, the first pressure tap arranged upstream of the break-away edge and both the second and third pressure taps downstream thereof, one normal vector substantially axis-parallel to the second pressure tap and one normal vector perpendicular to the third pressure tap, the second pressure tap point positioned at or close to a pressure minimum.

Abstract: A gas separator for separating a multiphase medium containing a gas and a liquid includes a tubular basic unit having a longitudinal axis, an intake for a gaseous medium, a liquid outlet and a gas outlet. The tubular basic unit has an intake region and a discharge region. The gas separator includes, between the intake region and the discharge region, a weir having a guiding surface, over which the medium can flow to form a shallow water region. The gas contained in the medium can escape from the medium in the shallow water region and be led away from the gas separator through the gas outlet. The disclosure is also directed to an apparatus for registering flow of at least one component of a multiphase medium.
