Abstract
An apparatus for measuring the temperature of a flowing fluid in a pipe. The apparatus includes a mechanism for actively testing the flowing fluid with acoustic energy and producing a test signal corresponding to the temperature of the fluid. The testing mechanism is disposed on the outside of the pipe and acoustic energy follows a path through the pipe wall. Additionally, the apparatus includes a signal processing mechanism for determining the temperature of the fluid based on the test signal. The testing mechanism is in communication with the signal processing mechanism.
