Abstract:
1. A method for system- and/or process-monitoring in the case of an ultrasonic flow-measuring device having a plurality of measuring channels, wherein a medium flows through a pipeline or measuring tube in the direction of a longitudinal axis of the pipeline or measuring tube, comprising the steps of: coupling ultrasonic measuring signals into the pipeline or measuring tube and out of the pipeline or measuring tube in such a manner that they travel through the medium on different sound paths; detecting the ultrasonic measuring signals in the individual measuring channels after passage through the pipeline or measuring tube; ascertaining at least one actual quantity describing the ultrasonic measuring signal of each measuring channel; comprising the actual quantity with a desired quantity captured under predetermined system or process conditions; and in the case of a deviation between the ascertained, actual quantity and the captured, desired quantity, a report is output.
