In the chemical industry, the fluidized bed reaction is a very complex chemical reaction in the polymerization reaction.The bulk density of the fluidized bed reaction is the key reference parameter of the fluidized reaction. So it is very important to accurately measure the bulk density data. The nuclear densitometer described in this paper is used to measure and solve the bulk density of a measuring instrument. Nuclear densitometer is a kind of instrument to detect the density of the medium. The measured data of the densitometer are used as the basis for safety overrun warning and overrun control in the measurement of the bed height of the single petrified polyethylene fluidized bed. Reasonable selection of nuclear densitometer and effective use of the advantages of accuracy and reliability of nuclear densitometer detection data play an important role in ensuring the precise control of fluidized bed height. In the application of the application of the device, the nuclear densitometer has a good effect, which provides an important parameter index and reference for the polymerization reaction control.
