| Summary: | The invention provides a non-intrusive method of characterizing flow disturbances of a fluid inside a cylindrical pipe (
2
). According to the invention, in order to determine flow disturbances, the method consists in using variation in the pressure of the fluid as a first indicator:
by placing at least one clamping collar around the pipe, the collar being provided with at least one deformation sensor sensitive to the deformation to which the pipe is subject due to variations of fluid pressure;
by measuring the deformation variations detected by the deformation sensor; and
by determining the variations of fluid pressure inside the pipe from measurements of deformation variations detected by said sensor. |
