Annotation

An extension of a recently proposed compensation technique [1, 2] is elaborated to measure the thermal expansion coefficient of conducting fluids. The method is based on simultaneously exerting two modulation effects of different physical natures on a studied sample. This technique enables direct local measurements of the thermal expansion coefficient expressed in absolute units.
