The BZPLS-1 gamma ray level gauge is a nuclear measurement and control instrument. It is made by applying the principle that gamma rays undergo varying degrees of intensity attenuation when penetrating various substances. It can be installed on the exterior of various shapes of containers being measured, such as balls, tanks, silos, chutes, pipelines, etc. This is a non-contact and non intrusive measurement method used to detect the position of liquids, slurries, or solid materials stored in the container, and is therefore not affected by changes in parameters such as pressure, temperature, density, viscosity, etc. of the tested material. The BZPLS-1 gamma ray level gauge has a reasonable design structure and is a fully enclosed metal shell structure. Therefore, it can be applied to various harsh measurement environments and can work normally for a long time. It operates safely and reliably and is suitable for level measurement in any sealed or unsealed container. This instrument outputs switch signals through relays for control or alarm purposes. The BZPLS-1 gamma ray level gauge was designed with extensive reference to the structural advantages and technical performance of the latest similar products from the United States, Germany, and other countries, and used as the basis for its structure and technical performance. This product series has passed the prototype appraisal of the Ionizing Radiation Department of the China Institute of Metrology and the appraisal of the Provincial Science and Technology Commission.
