Abstract:
1. An apparatus for positioning a clamp-on flow measuring device on a containment, through which a medium is flowing, comprising: 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 said 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, on the basis of a comparison of the calculated, desired variable with the corresponding, measured, actual variable, determines whether said ultrasonic transducers are optimally positioned or whether the positions of said ultrasonic transducers need to be changed; and an indicating unit, which indicates to operating personnel a required change in position and/or the direction in which a change in position needs to occur.
