Abstract: An adapter comprises a connecting nozzle, a connecting nozzle as well as a connecting nozzle. The free nozzle ends of the connecting nozzles are adapted to be connected to line ends of fluid lines. The adapter includes, for guiding flowing fluid in and then out, two mutually separated, tubular flow channels, of which a flow channel extends from a flow opening located in the free nozzle end of the connecting nozzle to a flow opening located in the free nozzle end of the connecting nozzle and a flow channel extends from a flow opening located in the free nozzle end of the connecting nozzle to a flow opening located in the free nozzle end. Moreover, the adapter includes, bordering on a region of the free nozzle end located between the flow openings a projection, which extends from the nozzle end with a length to a free projection end remote therefrom. A fluid line system formed by means of the adapter comprises, furthermore, a fluid line with, enveloped by a wall, a lumen, which extends from a flow opening located in a line end of the fluid line both to a flow opening located in a line end of the fluid line as well as also to a flow opening located spaced from the flow opening in the line end. The fluid line can be connected with its line end to the connecting nozzle of the adapter in such a manner that the projection protrudes inwardly into the lumen of the fluid line to form two tubular chambers of the fluid line mutually separated by the projection and adapted for guiding through flowing fluid.

Abstract: A method for determining compressibility of a flowing fluid includes: using a pump, driving a volume flow of the fluid through a measuring tube of a vibronic densimeter at a first pressure maintained using a throttle; determining a first density measured value of the fluid at the first pressure; determining a first pressure measured value at the first pressure; driving a volume flow of the fluid through the densimeter at a second pressure; determining a second density measured value at the second pressure different from the first pressure; determining a second pressure measured value at the second pressure; determining compressibility of the fluid based on the first density measured value, the second density measured value, the first pressure measured value and the second pressure measured value assuming the composition of the fluid is unchanged between the registering of the first density measured value and the second density measured value.
