Abstract: A separation assembly for the flow measurement of a gas flow and a liquid flow of a multiphase fluid includes separator with a housing and a separation element inside the housing. The separation element provides the fluid to rotate at high-speed causing strong centrifugal forces on the multiphase fluid. The housing has an inlet for a multiphase mixture and two outlets, one primarily for pre-separated gas and the second primarily for pre-separated liquid. These outlets lead to a regulator. The regulator is part of the separation assembly and includes at least two outlets, one for gas and one for liquid. The regulator ensures the proportional regulation and the final separation of gas and liquid phases over an entire flow rate to provide monophase liquid and gas at the outlets of the regulator.

Abstract: An arrangement for measuring density of flowable media includes: a fluid path for conveying a medium; a pump for driving a defined volume flow of the medium in the fluid path; a pressure difference measuring arrangement for registering a pressure drop due to the volume flow of the medium between first and second pressure taps in the fluid path; a densimeter having at least one oscillator, which has at least one oscillatable measuring tube for conveying the medium, at least one exciter mechanism for exciting oscillations of the measuring tube, and at least one sensor arrangement for registering at least one oscillatory characteristic of the oscillator. The at least one measuring tube is arranged in the fluid path. An evaluation apparatus ascertains the density of the medium based on the volume flow, the volume flow dependent pressure drop and the at least one oscillatory characteristic of the oscillator.

Abstract: A method for ascertaining a Reynolds number compensated flow velocity and/or a Reynolds number compensated flow (G) by a Coriolis flow measuring device, comprising steps as follows: a. ascertaining at least one meter factor (C) during a calibration time interval in a calibration plant (a) based on measured values (A and B) of the Coriolis flow measuring device and a piston test apparatus of the calibration plant (a) by an evaluation unit of the calibration plant (a); b. transmitting the meter factor (C) from the evaluation unit of the calibration plant (a) to an evaluation unit of the Coriolis-flow measuring device; c. associating a Reynolds number (H) with this meter factor (D) while the Coriolis flow measuring device is connected to the calibration plant (a), and storing at least one data set of at least one number pair (D), in each case, of a Reynolds number and a meter factor, in the Coriolis flow measuring device; d.
