ABSTRACT:
A fluid-filled pipe is investigated by a non-intrusive procedure to determine whether the fluid is liquid or gaseous, whether it is flowing or static, the direction of flow if it is flowing, the approximate pressure if it is a gas, and the rate of flow if it is a gas. The results are obtained by applying a heater to the surface of the pipeline and measuring the upstream and downstream temperatures of the surface of the pipe wall before and after the beginning of the application of heat. Some of the data generated is compared with data from another source to assist in the determination of the physical characteristics to be ascertained.
