Abstract
A method for ascertaining a compensated flow and/or a compensated flow velocity, wherein the compensation of a flow related measurement error occurs in the context of a flow measurement with a two path measuring of an ultrasonic, flow measuring device, comprising: an arrangement of at least two ultrasonic transducers pairs on a tube, or pipe, wherein the ultrasonic transducers are in a 180°, two path, one traverse, or a 90°, two path, two traverse arrangement, by means of an evaluation unit of a flow measuring device and/or a computer, characterized by steps as follows: a) feeding information relative to the type of a flow influencing, tube, or pipe, element into the evaluation unit and/or into the computer; b) feeding information relative to distance (xa-xd) of the arrangement of the ultrasonic transducer pairs from the flow influencing, tube, or pipe, element into the evaluation unit and/or into the computer; c) compensating a measurement error by means of a correction factor kD as a function of information from steps a) and b); and d) ascertaining a flow corrected by the correction factor kD and/or a flow velocity corrected by the correction factor kD, as well as an ultrasonic, …
