Problems solved by technology

However, these aspects do not provide an accurate measurement of the concentration of the individual analytes in the mixture at the limits of their minimum and maximum concentrations
[0007] With existing sensor systems, none brings the combination of low cost, high sensitivity, good signal-to-noise ratio, high selectivity, high accuracy, and high data acquisition speed
Furthermore, no existing system has been described that is capable of accurately characterizing or quantifying fluid mixtures in which one of the fluids is at low concentrations

Embodiment Construction

[0020] Reference will now be made in detail below to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0021] As will be discussed in more detail below, embodiments of the present invention provide low cost systems for sensing levels of different components in multiphase fluids. Multiphase fluids include multiple independent components. For example, the oil and water components make up the majority of the volume in an oil-water emulsion. An important aspect of oilfield management and wastewater management is determining the level of water present in the retrieved emulsion. Additionally, in some of these systems, demulsifiers are used with the emulsion to separate the emulsion into its different components. The effectiveness of these demulsifiers needs to be tested by using the demulsifier o...

Abstract

A system for measuring component fluid levels in a multi-phase fluid is provided. The system includes a sensing assembly. The sensing assembly includes a primary coil and at least one secondary coil. The primary coil is wound around a sampling container that holds the multi-phase fluid. The secondary coil is disposed proximate to the primary coil and each of the at least one secondary coil is electrically connected to at least one capacitive element. Further, the system includes an analyzer that is inductively coupled to the at least one secondary coil. The analyzer is configured to measure a response of the at least one secondary coil in response to an excitation signal provided to the primary coil.

Description

technical field [0001] The present invention relates generally to sensors, and in particular to level sensors for measuring fluid levels in multiphase fluids. Background technique [0002] Measurement of the composition of multiphase fluids such as emulsions is an important application in many industries. Determination of the oil and water content of emulsions is necessary at different stages in crude oil production and refining. Emulsion characteristics are important in oilfield management, separators, desalters, wastewater management systems, and oil quality control systems. It is important to know the levels of oil and water in the mixture obtained from a particular field to understand the general health of the field and to improve the productivity and capacity of the field. [0003] In a container system such as a separator, oil and water and other components present in an emulsion obtained from a well are separated from each other by gravity and the density difference...
