Abstract
An apparatus for the positioning of a clamp-on flow measuring device on a containment, which has a medium flowing through it. The apparatus includes at least two ultrasonic transducers, which emit measuring signals into the containment and/or receive measuring signals from the containment, a positioning unit for the variable positioning of the ultrasonic transducers on the containment, a control/evaluation unit, which calculates from predetermined process and/or system variables a characteristic, desired variable of the measuring signals and which determines on the basis of a comparison of the calculated, desired variable with the corresponding, measured, actual variable, whether the ultrasonic transducers are optimally positioned or whether the position of the ultrasonic transducers need to be changed, and an indicating unit, which indicates to operating personnel a required change of position and/or the direction in which a change of position needs to be made.
