Abstract:
Magnetic-inductive flow meters are used to measure volume flow of electrically conduction fluids. The usually required minimum conductivity is discussed here in detail by a numerical analysis using the drift-diffusion model for the solved ions. It turns out that the minimum concentration is already reached through the protons and hydroxyl ions that are present even in pure water. Even non-conducting but polarizable liquids exhibit a magnetic-inductive effect.
