Radiation based level sensor has a radioactive source as a transmitter and is paired with a detector at the opposite outside of the tank With radiometric level and density measurement, only gamma radiation is used To determine the level of material, the detector looks for a.
Nuclear Level Measurement – Instrumentation and Control Engineering
Demystifying radiometric level measurement ents since the 1950s
That’s right, radiometric level measurement has been with us since the days of elvis presley, poodle sk rts, and.
The concept of nuclear level sensors is based on the fact that certain types of nuclear radiation easily penetrate the walls of industrial vessels, but is attenuated by traveling through the bulk of material. A radiation source is placed on one side of the vessel and a detector is placed on the other As the level inside the vessel changes, the amount of radiation reaching the. By placing a radioactive source on one side of the vessel and measuring the radiation reaching the other side of the vessel, an approximate indication of level within that vessel may be obtained.
Nuclear level measurement with radiation works on the principle of passing gamma radiation through the material to be measured As the radiation passes through. The gamma source, a cesium or cobalt isotope, emits gamma radiation which is attenuated as it passes through materials The measuring effect results from the absorption of radiation by the product to be.
The continuous measurement of level uses a radiation field over the whole measuring range
If the level rises within the range of the radiation field, the attenuation becomes stronger and.
