- the invention relates to a Coriolis flow meter for preferably pharmaceutical bioprocess applications.
- a Coriolis flow meter is a meter for detecting a mass flow, a viscosity, a density and/or a variable of a flowable medium derived therefrom.
- Field devices in process measurement technology with a vibration-type sensor and, in particular, Coriolis flowmeters have been known for many years.
- the basic structure of such a measuring device is, for example, in
- Coriolis flowmeters typically have at least one or more oscillatable measuring tubes, which can be made to oscillate by means of an oscillating exciter. These vibrations are transmitted over the length of the pipe and are varied by the type of medium in the measuring pipe and its flow rate.
- a vibration sensor or, in particular, two vibration sensors spaced apart from one another can record the varied vibrations in the form of a measurement signal or a plurality of measurement signals at another point on the measuring tube.
- An evaluation unit is then set up to determine the mass flow rate, the viscosity and/or the density of the medium from the measurement signal or signals.
- WO 2011/099989 A1 teaches a method for producing a monolithic measuring tube arrangement of a Coriolis flowmeter with curved measuring tubes, the measuring tube body of the respective measuring tubes first being formed solidly from a polymer and the channel for guiding the flowable medium then being incorporated in a clamping manner becomes.
