1. 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.

11. 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. - View Dependent Claims (12, 13, 14)
