Abstract
A method for measuring properties of a fluid that includes oscillating a tuning fork resonator in a fluid. The invention is particularly suitable for in-line monitoring of various physical and electrical properties of fluids flowing in a conduit.
Claims14
A method for in-line monitoring of a fluid composition, the method comprising:
- placing a tuning fork resonator in contact with the fluid composition in a conduit;
- oscillating the resonator while the fluid composition is flowing in the conduit;
- monitoring the resonator to obtain a resonator response;
- and
- determining at least two properties of the fluid composition based on the resonator response, where at least one of the properties is an electrical property.

A method for in-line monitoring of a fluid composition, the method comprising:
- calibrating a tuning fork resonator against a standard fluid or a number of standard fluids having known properties to obtain calibration data;
- placing the resonator in contact with the fluid composition in a conduit;
- oscillating the resonator while the fluid composition is flowing the conduit;
- monitoring the resonator to obtain a resonator response;
- and
- determining at least two properties based on the calibration data and the resonator response, where at least one of the properties is an electrical property.
