Apparatus for determining fluid flow

An apparatus (10) for measuring the temperature of a flowing fluid (11) in a pipe (12) characterized by: means (14, 16) for actively testing the flowing fluid (11) with acoustic energy and producing a test signal corresponding to the temperature of the fluid (11), said testing means (14, 16) dispose...

More Information
Summary:An apparatus (10) for measuring the temperature of a flowing fluid (11) in a pipe (12) characterized by: means (14, 16) for actively testing the flowing fluid (11) with acoustic energy and producing a test signal corresponding to the temperature of the fluid (11), said testing means (14, 16) disposed on the outside of the pipe (12) and acoustic energy follows a path through the pipe wall; and signal processing means (26) for determining the temperature of the fluid (11) based on the test signal, said testing means (14, 16) in communication with said signal processing means (26).
