Magnetic densimeters: design and operation

Presented here is a comparison of two magnetic densimeters, one using a r.f. sensing system and one using an optical sensing system. Both systems have the same control system. Based on a series of experiments, it appears that the optical sensing densimeter is much easier to handle than the one using r.f. sensing. This is because the r.f. system is much more sensitive to stray electromagnetic radiation.

Presented here also is a method for determining the partial specific volumes of each component in a multi-component system, prior to and after the interaction of these components using a magnetic densimeter.
