Abstract
A Coriolis mass flowmeter and a measuring tube unit for use in the Coriolis mass flowmeter with an inlet end and an outlet end, at least two measuring tubes and at least two transition pieces. In each case, one transition piece is arranged on a measuring tube at the inlet end. Each measuring tube has a measuring tube cross section and each transition piece has a transition piece cross section at the inlet. The transition piece is designed in one piece with the associated measuring tube, and the transition piece cross section deviates in its shape and size from the associated measuring tube cross section, the measuring tubes being arranged and aligned in such a manner that the transition piece cross sections form an overall cross section and thus a flow divider.
Claims15
A measuring tube unit for use in a Coriolis mass flowmeter with an inlet end and an outlet end, comprising:
- at least two measuring tubes and at least two transition pieces, wherein each transition piece is arranged on a respective one of the measuring tubes at an inlet end thereof, and wherein each measuring tube has a measuring tube cross section and each transition piece has a transition piece cross section at the inlet end,
- wherein the transition piece is formed in one piece with the respective one of the measuring tubes, and
- wherein the transition piece cross section deviates in at least one shape and size from the cross section of the respective one of the measuring tubes, and
- wherein the measuring tubes are arranged and aligned in such a manner that the transition piece cross sections form an overall cross section and thus a flow divider.
Coriolis mass flow meter, comprising:
- a control and evaluation unit for controlling oscillation excitation and for evaluating and displaying recorded measured data, and
- a measuring tube unit having at least two measuring tubes and at least two transition pieces, wherein each transition piece is arranged on a respective one of the measuring tubes at an inlet end thereof, and wherein each measuring tube has a measuring tube cross section and each transition piece has a transition piece cross section at the inlet end,
- wherein the transition piece is formed in one piece with the respective one of the measuring tubes, and
- wherein the transition piece cross section deviates in at least one of shape and size from the cross section of the respective one of the measuring tubes, and
- wherein the measuring tubes are arranged and aligned in such a manner that the transition piece cross sections form an overall cross section and thus a flow divider.
