Radioactive Level Meter
Na-22 Radioactive Level Measurement-Exemption from Approval
The Radioactive Level Meter manufactured by VGO Smart includes Na-22 Radioactive Level Measurement, Cs-137 Radioactive Level Measurement, Co-60 Radioactive Level Measurement, and so on.In China, users who purchase our company's Na-22 radioactive sources can use Na-22 radioactive sources and Na-22 radioactive level meters without going through exemption approval procedures, and there is no need to build a radioactive source warehouse, and our company is responsible for handling radioactive source recycling. The same applies to countries and regions with similar laws and regulations on radioactive sources management as China.
DPRO-66 Nuclear Level Meter with Na-22 radioactive sources is the latest application achievement of VGO Smart in industrial nuclear measurement technology. It is very different from the conventional nuclear level meters, which use Cs-137 or Co-60 radioactive sources.The activity of Na-22 radioactive sources is less than 1000kbq, and is very low.
The Radioactive Level Meter can be used to monitor and control the level or interface of liquids, slurries and solids in a variety of reactors, containers and silos.
In addition, we have mastered ultra-sensitive radiation measurement technology and cutting-edge software processing technology. Through PROWIN debugging software, we can realize one-click backup and restoration of system parameters to ensure data security.
Ultra-high Sensitivity Density/Concentration Measurement System
The DET-7000 series ultra-high sensitivity detector and the intelligent transmitter TRA-9861 are used for detection and analysis of low intensity γ rays of Na-22 passing through pipes and media. The system can output medium level directly or mass flow rate in conjunction with volume.

Na-22 Radioactive Source Exemption from Approval
The activity of the Na-22 radioactive sources used in the Na-22 Level Meter is less than 27μCi (1×1000kbq). The activity range of radioactive sources is below Class V within the scope of exempt administration. The users can use the instruments that use the Na-22 radioactive sources without supervision and without going through relevant procedures.
