LPRO-90 Radioactive Material Level Meter raises the standard for non-contact level measuring systems. This simple, reliable, non-plug-in measurement system can be used to monitor and control the level or interface of liquids, slurries, and solids in a variety of reactors, containers, and silos. The measurement is not affected by the size and shape of the container, nor by high temperature, high pressure or vacuum, corrosion, wear, steam and dust. Due to the use of highly sensitive scintillation detector, coupled with the detailed and accurate design of professional and technical personnel, under the premise of ensuring the safety of users, to achieve stable, continuous and reliable measurement of material level.
Measurement Principle
LPRO-90 Radioactive Material Level Meter uses the physical principle of attenuation when gamma rays pass through the material{exponential attenuation law}:when the container size is fixed, after determining the radioactive source, the high of the material in the container is the only factor affecting the measurement results.
LPRO-90 Radioactive Material Level Meter is composed of shielded radioactive source, scintillation detector and intelligent transmitter. The radioactive source is installed on one side of the container and the detector is installed on the opposite side. Gamma rays pass through the container and process medium and are picked up by the detector. When the height of the process medium changes, the signal intensity received by the detector changes accordingly. When the material level rises, the detector signal intensity weakens. On the contrary, the signal strength increases. The intelligent transmitter converts the electrical signal transmitted from the detector into the corresponding material level value.

Radioactive source with Pneumatic Lead Canister.
Radioactive materials are tightly enclosed in double-layer stainless steel sleeves, under high temperature, high pressure, strong impact and other extreme conditions will not leak out. According to different measurement tasks, different types and activities of radioactive source can be selected. The radioactive source is semi-permanently fixed in the lead canister, and the resulting rays are directed at the detector through slits in the canister. Lead tanks are designed and manufactured according to the activity of radioactive sources to ensure that the radiation received by workers is far below the national standard. The lead can with pneumatic actuating switch can be locked in the on/off position. The switch position is not in the same direction as the ray outlet to reduce the radiation exposure of maintenance personnel. Manual switch mode can also be switched.
