摘要： Measuring system and method for determining and/or monitoring flow of a measured medium through a measuring tube with a first ultrasonic sensor and at least a second ultrasonic sensor, wherein the first ultrasonic sensor has at least one electromechanical ultrasonic transducer element and is placeable in a first region of the measuring tube, and wherein the second ultrasonic sensor has at least two electromechanical ultrasonic transducer elements and is placeable in a second region of the measuring tube in such a manner, that the ultrasonic signals transmittable through the measured medium from the first ultrasonic sensor are receivable by the second ultrasonic sensor, and that the ultrasonic signals transmittable through the measured medium from the second ultrasonic sensor are receivable by the first ultrasonic sensor, and with at least one control/evaluation unit, which, on the basis of the ultrasonic-measuring signals, or on the basis of measurement data, which are derived from the ultrasonic measuring signals, ascertains the volume flow and/or the mass flow of the measured medium flowing in the measuring tube by means of a travel-time difference method. During a diagnostic phase, ultrasonic signals are transmitted from the first ultrasonic sensor through the measured medium to the second ultrasonic sensor, and at least one process variable is ascertained and/or derived from the received ultrasonic signals for each electromechanical ultrasonic transducer element of the second ultrasonic sensor, and the electromechanical ultrasonic transducer elements of the second ultrasonic sensor which are to be active in a following measuring phase are selected on the basis of the process variable of the received ultrasonic signals.
