Abstract

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. A strain gauge and/or the second longitudinal section of the pipeline are/is at a spacing from at least one end of the pipeline, which spacing corresponds to at least an internal diameter of the pipeline. By comparing strain gauge measurements, the wall thickness is determinable.
