Abstract:
Methods for determining a density of a fluid are provided. The method can include passing the fluid through a conduit, measuring a vibration of the conduit by distributed acoustic sensing via a fiber optic cable coupled to the conduit, and generating a vibrational signal indicative of the measured vibration. At least a portion of the vibration of the conduit can be produced by the fluid passing therethrough. The method can also include measuring a temperature of the conduit and generating a temperature signal indicative of the temperature. The method can further include calculating the density of the fluid passing through the conduit by using the vibrational signal and the temperature signal.

Claim (Index 17):
A method for determining a density of a fluid, comprising:\n flowing, at a time the density of the fluid is to be determined, the fluid through a conduit having an outer surface, wherein the fluid comprises a plurality of particles disposed in a liquid, a gas, or a mixture thereof; measuring, at the time the density of the fluid is to be determined, a vibration of the conduit by distributed acoustic sensing via a fiber optic cable coupled to the outer surface of the conduit and generating a vibrational signal indicative of the vibration, wherein at least a portion of the vibration of the conduit is produced by the fluid passing through the conduit; measuring, at the time the density of the fluid is to be determined, a temperature of the outer surface of the conduit by distributed temperature sensing via the fiber optic cable and generating a temperature signal indicative of the temperature; adjusting, at the time the density of the fluid is to be determined, a model of the conduit using the vibrational signal and the temperature signal; calculating the density of the fluid passing through the conduit by using the vibrational signal and the temperature signal in the model; and wherein the model comprises solving the following equation for \u03c1 F : \u03c1 F = E \ue8a0 ( T ) \ue89e I \ue89e \ue89e \u03b2 4 \u03c0 \ue89e \ue89e a 2 \ue89e \u03c9 2 - b 2 - a 2 a 2 \ue89e \u03c1 P , wherein:\n \u03c1 F  is the density of the fluid; \n \u03c1 P  is the density of the conduit material; \n a is the inner radii of the conduit; \n b is the outer radii of the conduit; \n E(T) is the Young's modulus of the conduit material as a function of the temperature of the conduit; \n I is the area moment of inertia of the conduit; \n \u03c9 is the angular frequency of the conduit; \n \u03b2 4 = ( m P + m F ) \ue89e \u03c9 2 E \ue8a0 ( T ) \ue89e I ; m P =\u03c0(b 2 \u2212a 2 )\u03c1 P  and is the linear density of the conduit; and m F =\u03c0a 2 \u03c1 F  and is the linear density of the fluid.
