Problem Statement

Nan Gall are developing a densitometer for application down oil wells, based on a transducer supplied by Solartron. The transducer is not designed for such environments and the Study Group was asked to consider the following questions. What is the best mode of operation, in particular to ensure that the results are independent of viscosity? What are the effects of enclosing the device in the pressure rated housings that are required for deployment in oil wells? Finally, how does the device respond to an inhomogeneous fluid?
