摘要
A pipeline for conveying concrete determines a pressure in and/or a wall thickness of the pipeline, wherein a first length portion of the pipeline has a first wall thickness and a second length portion of the pipeline has a second wall thickness greater than the first wall thickness. The determination is made using a first strain gauge on an outer side of the first length portion and a second strain gauge on an outer side of the second length portion, wherein the strain gauges are each fixedly applied to the outer side of the length portions. By comparison of the measurements at the two strain gauges, it is possible to determine a wall thickness by determining a strain of the pipeline owing to a decrease in the wall thickness.
