Nuclear level meters are commonly used in the measurement of catalyst level in CCR platforming,and the accurate monitoring of the level plays a crucial role in the level control of catalyst regeneration unit.This paper briefly describes the measurement principle of nuclear level meters,compares the typical configurations,specification parameters and calibration methods of nuclear level meters,emphasizes the safety protection requirements of national standards for nuclear level meters,and installation precautions in engineering projects.Taking a 2.2 million ton/year CCR platforming unit as an example,analyzed the practical application of nuclear level meters,and providing reference for the selection and engineering design of nuclear level meters in CCR platforming.
