In radiometric, i.e. radiation-based, level measurement, a slightly radioactive isotope emits focused gamma rays. The sensor, which is mounted on the opposite side of the vessel, receives this radiation. Since gamma rays are attenuated when penetrating matter, the sensor can calculate level, point level, density or mass flow from the intensity of the incoming radiation.
Maximum operational reliability even in the harshest environments
Measurement is independent of pressure, temperature and product aggressiveness
Measuring system can be installed on the outside of a vessel during ongoing production
