1. A computer-implemented method for determining flow information of a well producing fluid from a subsurface formation comprising:
obtaining at least one first production measurement from the well;
obtaining, with a sensor, a first measurement of an acoustic signal generated by the fluid oscillating in an asymmetric acoustic device, wherein the asymmetric acoustic device is configured to cause the fluid to oscillate as the fluid flows through the asymmetric acoustic device;
inputting the first measurement and the at least one first production measurement into a virtual flow meter; and
determining, via the virtual flow meter, a multi-phase flow rate of the fluid based on the first measurement and the at least one first production measurement.
