Abstract
A flowmeter has a guide structure that can have medium flowing through it and which preferably operates using the Coriolis principle. To provide a flowmeter that allows a high as possible measuring accuracy with a space requirement that is as small as possible, at least one sensor element is applied on an outer surface of the guide structure for determining and/or monitoring at least one process variable.
Claims2
Flowmeter, comprising:
- a guide structure through which a medium is flowable, and
- at least two electrical sensor elements applied to an outer surface of said guide structure,
- one of said at least two sensor elements being a strain-measuring element and another of said at least two sensor elements being a temperature-measuring element, and
- said strain-measuring element and said temperature-measuring element being electrically connected in series, and
- wherein measurements obtained by the strain-measuring element and said temperature-measuring element are obtained directly at a point in the series connection between them;
- wherein said guide structure has at least two measuring tubes,
- wherein each sensor element of said at least two sensor elements is arranged on an outer surface of one of said at least two measuring tubes, and
- wherein relative circumferential position of said at least two sensor elements around the respective measuring tube are different, and
- wherein said at least two sensor elements are arranged on a carrier element.
