Abstract:
A measuring system and method for determining and/or monitoring the flow of a measured medium through a measuring tube with a first ultrasonic sensor and at least a second ultrasonic sensor. The first Ultrasonic sensor is placeable in a first region of the measuring tube, and the second ultrasonic sensor is placeable in a second region of the measuring tube. The ultrasonic signals transmittable through the measured medium from the first ultrasonic sensor are receivable by the second ultrasonic sensor, and the ultrasonic signals transmittable through the measured medium from the second ultrasonic sensor are receivable by the first ultrasonic sensor. A control/evaluation unit 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.
