Abstract
A method for determining solid content concentration in a fluid flow includes measuring a noise signal generated by a fluid flow and correlating the noise signal to the solid content. The noise signal may be correlated to represent the solid content concentration such as by applying one or more filters to the noise signal or applying one or more physical or numerical methods to the noise signal. For example, the fluid flow may be pressurized to a selected level to collapse gas bubbled entrained in the fluid flow, thereby eliminating or substantially reducing a component of the noise signal unrelated to the solid content.
Claims24
A method for ascertaining a solid content in a fluid flow comprising:
- receiving a signal from a flow meter measuring a fluid flow, the signal having a noise signal caused, at least in part, by solids in the fluid flow;
- and
- determining the solid content in the fluid flow based on the noise signal.
An article of manufacture comprising a machine-readable medium storing instructions for causing one or more processors to perform operations comprising:
- receiving data from a flow meter measuring a fluid flow, the signal having a noise signal caused, at least in part, by solids in the fluid flow;
- and
- determining the solid content based on the noise signal.
A method for controlling a solid content in a fluid flow comprising:
- receiving a signal from a flow meter measuring a fluid flow, the signal having a noise signal caused, at least in part, by solids in the fluid flow;
- determining the solid content of the fluid flow utilizing the noise signal;
- and
- adjusting an amount of the solid added to the fluid flow based on the determined solid content.
