Understanding How Radiometric (Radiation-based) Level Measurement Works

Radiometric (also known as radiation-based) level measurement uses a very slightly radioactive isotope that emits focused gamma rays. A sensor, which is mounted on the opposite side of the vessel, receives this radiation. Because 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.

Advantages are:
  • 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
