The present invention relates to a method and system for measuring characteristics of a multiphase flow from structural vibration signals. In this sense, the objectives of the invention are achieved by means of a method for measuring characteristics of a multiphase flow from structural vibration signals which comprises: obtaining, by means of acceleration sensors (V01, V02, T00) externally fixed to a pipeline, signals based on pipeline internal flow vibration; processing, by means of a processing device, the obtained signals; and determining a dispersion curve fitting coefficient to determine the void fraction of the mixture.

In some embodiments, an apparatus includes a base structure and a tube. The tube has a first tube portion, a second tube portion substantially parallel to the first tube portion, an inlet portion, and an outlet portion. The tube is configured to have a material pass from the inlet portion to the outlet portion. The apparatus further includes a drive element in contact with the tube. The drive element is configured to vibrate the tube such that the first tube portion conducts vibrational movements out of phase with vibrational movements of the second tube portion. The apparatus also includes a sensing element, at least a portion of which is in contact with the tube. The sensing element is configured to sense deflections of the first tube portion and the second tube portion such that at least one property of the material is determined.

The approach presented here relates to an analysis device (100) for analyzing a viscosity of a fluid (217). The analysis device (100) comprises a detection device (110) and a provisioning device (115). The detection device (110) is formed to determine the viscosity of the fluid (217) using at least one Doppler parameter of a Doppler spectrum of the fluid (217). The provisioning device (115) is formed to provide or transmit a viscosity signal that represents the viscosity determined by the detection device (110).

A method of monitoring characteristics of a viscosified fluid in a substantially continuous manner. Devices and techniques for such methods include use of an in-line Coriolis flowmeter to continuously circulate a portion of the viscosified fluid therein for analysis as the fluid may be directed to a blender for combining with a constituent such as proppant for forming a fracturing slurry. Devices and techniques herein allow for real-time monitoring and adjustment of the developing viscosified fluid and/or halting of the fracturing application depending on results of the ongoing monitoring.
