Abstract
Downhole tools for measuring properties of a fluid include a sample chamber configured to receive the fluid, a field responsive material ('FRM') arranged with an interface between the field responsive material and the fluid under test in the sample chamber. The field responsive material is tunable to change an acoustic impedance of the field responsive material in response to application of an applied field. A field generator is arranged in relation to the field responsive material, the field generator configured to generate and apply a field to the field responsive material. An acoustic transducer is arranged to direct acoustic energy into and through the field responsive material toward the interface between the field responsive material and the fluid and configured to detect reflections of acoustic energy that reflect from the interface.
