A sensor includes a resonant transducer, the resonant transducer being configured to determine the composition of an emulsion or other dispersion. The resonant transducer has a sampling cell, a bottom winding disposed around the sampling cell, and a top winding disposed around the bottom winding. The composition of the dispersion is determined by measuring the complex impedance spectrum values of the mixture of the dispersion and applying multivariate data analysis to the values.

Sensor systems for measuring an interface level in a multi-phase fluid composition

A sensor includes a resonant transducer, the resonant transducer being configured to determine the composition of an emulsion. The composition of the emulsion is determined by measuring the complex impedance spectrum values of the mixture of the emulsion and applying multivariate data analysis to the values.

A pressure management system for sensors is provided. The system includes a sampling assembly. The sampling assembly is configured to hold a first portion of a test fluid. Further, the system includes at least one sensor disposed proximate to the sampling assembly. The sensor is configured to determine at least one property of the test fluid. The system also includes a housing that is disposed around the sampling assembly. The housing defines a fluid chamber that houses a balancing fluid. Furthermore, the system includes a flexible device disposed in the fluid chamber that draws a second portion of the test fluid. The flexible device is configured to balance pressure exerted by the test fluid on the sampling assembly by exerting pressure on the balancing fluid with the second portion of the test fluid.
