Abstract

In a method of measuring the fill level of a reactor in continuously operated polymerization processes using measurement of the respective phase interface in the reactor by means of ionizing radiation, at least one measuring unit comprising a radiation source which emits ionizing radiation and a corresponding detector is brought to the phase interface in the reactor and flexibly installed there, with the fill level of the reactor being measured by determining the phase interface by means of the radioactive backscattering measurement.
