Abstract
Disclosed is a flow meter with at least two measuring sensors, preferably ultrasonic sensors, spaced apart from each other, wherein the coupling of the measuring signals into and out of a fluid is performed via a coupling element which is inserted flush into a circumferential wall of a measuring channel.
Claims18
A flow meter having a measuring channel configured to be attached to a pipe, through which measuring channel a fluid flows and on which measuring channel a measuring unit is held, the measuring unit including at least two sensors, the at least two sensors spaced apart from each other and immersed in at least one recess of the measuring channel, wherein a coupling of measuring signals into or out of the fluid is performed via a respective coupling element, each of which accommodates at least one of the at least two sensors, wherein the coupling elements are inserted flush into a peripheral wall of the measuring channel, and further wherein each of the coupling elements includes a coupling wedge inclined with respect to a measuring channel axis and on which one of the at least two sensors rests, and further wherein:
- one of (1) at each coupling element, at least two sensors, are accommodated, and (2) at each coupling element, which coupling elements are arranged in pairs on a coupling side and on a decoupling side, respectively, one sensor is accommodated;
- in such a manner that at least two approximately parallel signal paths are formed.
