Abstract
A Coriolis mass flowmeter has a measuring tube that can be excited to oscillation, an oscillation driver and/or an oscillation sensor, wherein the oscillation driver and/or the oscillation sensor has a permanent magnet. The permanent magnet is arranged in a magnet holder so that a sure and simple fixation of the permanent magnet is achieved.
Claims15
A Coriolis mass flowmeter with a measuring tube that can be excited to oscillation, an oscillation driver and/or an oscillation sensor, the oscillation driver and/or the oscillation sensor having a permanent magnet characterized in that the permanent magnet has a magnet holder.
A Coriolis mass flowmeter having exactly two measuring tubes that can be excited to oscillation and a housing, wherein an end connection plate from a pipe to both measuring tubes is provided on each end of the measuring tube, characterized in that the end connection plates are attached to one another by means of a reinforcing bridge that is separate from the housing.
A Coriolis mass flowmeter having exactly two measuring tubes that can be excited to oscillation, wherein an end connection plate from a pipe to both measuring tubes and a flanged connection for connection to a process pipeworks are provided on each end of the measuring tube characterized in that the end connection plates and the flanged connection are made of one common component.
A Coriolis mass flowmeter having a measuring tube that can be excited to oscillation, a housing enclosing the measuring tube and an electronic converter, characterized in that the electronic converter is provided completely inside of the housing.
A Coriolis mass flowmeter having two measuring tubes, wherein two neighboring oscillation node plates are provided on one end of the measuring tube that connect the two measuring tubes to one another, characterized in that the angle between the planes of both oscillation node plates is determined in such a manner that the vibration of the measuring tubes is minimal up to a predetermined driving force.
A method for producing a Coriolis mass flowmeter having two measuring tubes, wherein two neighboring oscillation node plates are provided on one end of the measuring tubes that connect the measuring tubes to one another, characterized in that the angle between the planes of both oscillation node plates is determined in such a manner that the vibration of the measuring tubes is minimal up to a predetermined driving force.
