Generally, the newly installed pipeline conditions are better, and the measurement on the old pipeline must be understood. If the following defects exist, the installation location should be re-selected.
(1) The thickness of the pipe wall is uneven, and there is obvious roughness;
(2) The inner wall of the pipeline has a thick adhesion layer;
(3) The lining is separated from the inner wall of the pipeline, and there is an air sandwich.
In order to ensure measurement accuracy, the pipeline should be treated as follows during installation:
(1) Near the installation location of the transducer, the coating and rust on the tube wall should be cleaned to ensure that there is no roughness.
(2) When installing the transducer, it is necessary to evenly coat the surface of the pipeline with a layer of coupling agent, and extrude the bubbles and particles in the coupling agent, so that the transmitting surface of the transducer should be tightly attached to the pipe wall.
