A method and apparatus for measuring the signal viscosity a flue or the concentration in a flue sig as a function of the finely divided solids

摘要

The viscosity of a liquid or the concentration of solid matter suspended in a liquid is measured by determining the damping of a vibrating measuring body introduced in the liquid or the suspension, the body vibrating at resonance frequency. In a first embodiment the body is vibrated with constant vibration amplitude and the energy supplied is measured. In a second embodiment the body is vibrated with constant energy supplied and the vibration amplitude is measured.
