    Levelflex FMP51, FMP52, FMP54 Function and system design Measuring principle Basic principles The Levelflex is a "downward-looking" measuring system that functions according to the ToF method (ToF = Time of Flight). The distance from the reference point to the product surface is measured.
  • Page 7 Levelflex FMP51, FMP52, FMP54 Dielectric constant The dielectric constant (DC) of the medium has a direct impact on the degree of reflection of the highfrequency pulses. In the case of large DC values, such as for water or ammonia, there is strong pulse reflection while, with low DC values, such as for hydrocarbons, weak pulse reflection is experienced.

  • Page 40: Influence Of Gas Layer

    Levelflex FMP51, FMP52, FMP54 Influence of gas layer High pressures reduce the propagation velocity of the measuring signals in the gas/vapor above the fluid. This effect depends on the kind of gas/vapor and of its temperature. This results in a systematic measuring error that gets bigger as the distance increases between the reference point of the measurement (flange) and the product surface.
