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.

Abstract: A measurement system includes: a pipe insertable into the course of a pipeline; a bluff body arranged in the pipe and configured to generate vortices having a shedding frequency dependent on an instantaneous flow velocity of a fluid such that a Kármán vortex street is formed in the fluid flowing downstream of the bluff body; a vortex sensor arranged downstream of the bluff body, having a resonance frequency and configured to effect mechanical oscillations as to provide a vortex sensor signal including a first component representing oscillations of the vortex sensor with the shedding frequency and a second component representing the mechanical resonance frequency of the vortex sensor; and converter electronics for evaluating the vortex sensor signal and configured to determine whether and/or to what extent the fluid contains foreign substances and/or is a single- or multi-phase substance based on the first and second components of the vortex sensor signal.

Abstract: Disclosed is a method and a device for detecting a non-condensable portion of a medium, which has at least one condensable portion and is present at least partially in gaseous form, wherein in a first method step a temperature measuring device measures a temperature of the medium and a pressure measuring device measures a pressure of the medium, wherein in a second method step a ratio of the pressure to temperature is formed by means of an electronic measuring/operating circuit and this ratio is compared with a desired ratio of a desired pressure and a desired temperature, and wherein in a third method step the electronic measuring/operating circuit outputs a report in case of a minimum deviation of the ratio from the desired ratio.

Abstract: The flow conditioner comprises a diffusor with a guide system arranged within its lumen, a flow rectifier with a disc shaped flow obstruction arranged within its lumen, wherein the flow obstruction has a plurality of flow openings, as well as a confusor, wherein diffusor, flow rectifier and confusor are connected fluidically in series to form a flow path extending from a flow opening of the diffusor to a flow opening of the confusor and involving the lumina of diffusor, flow rectifier and confusor. The guide system of the diffusor includes a sleeve shaped deflection means as well as a plurality of mutually separated connecting elements connected both with the deflection means as well as with the wall of the diffusor. The guide system is so formed and so positioned that the deflection means is spaced from the wall of the diffusor and arranged coaxially with the lumen of the diffusor.

Abstract: The present disclosure relates to an assembly comprising a pressure tapping line having a first end and a second end. A pressure measuring device registers a pressure within the pressure tapping line and the pressure tapping line is adapted to be connected using the first end to a vapor conveying pipe or tube. The pressure measuring device is adapted to be connected to the second end of the pressure tapping line and the pressure tapping line has a sectionally bent trap adapted to contain a condensate of the vapor. The assembly is adapted to be applied outside and includes a wind protector to lessen atmospherically related air movements at least in the region of the trap.
