Abstract
Earlier work [C. A. Grimes et al., Smart Mater. Struct. 8, 639, (1999)] has shown that upon immersion in liquid the resonant frequency of a magnetoelastic sensor shifts linearly in response to the square root of the liquid density and viscosity product. It is shown that comparison between a pair of magnetoelastic sensors with different degrees of surface roughness can be used to simultaneously determine the liquid density and viscosity.Keywords
