Abstract (en)
[origin: WO0159427A1] The invention concerns a non-intrusive method for characterising flow perturbations of a fluid inside a cylindrical pipe (2), which consists in: using as first indicator for determining the flow perturbations the variation of the fluid pressure: by providing around the pipe, at least a clamping ring, provided with a deformation sensor sensitive to deformations to which the pipe is subjected following fluid pressure variations, by measuring the deformation variations detected by the deformation sensor, and determining the pressure variations inside the pipe on the basis of the measurements of deformation variations detected by said sensor.
