Abstract

A device for measuring the state of a phase change material inside a vessel, the device includes at least one optical fiber arranged inside the vessel, the optical fiber including a cladding around a core, a light source emitting light coupled into a first end of the at least one optical fiber at a wavelength λ, optical measuring devices for measuring the amount of light at the output at a second end of the at least one optical fiber. The at least one optical fiber also includes a plurality of sections with the cladding removed so that at these sections the core is in direct contact with the phase change material inside the vessel and where the refractive index at the wavelength λ of the core is higher than that of the phase change material in a first phase and lower in a second phase.
