Level Measurement for Industrial Applications

Contactless level measurement - invented by Berthold Technologies

Level measurement

In the process industry, precise systems for level and level switch measurement are fundamental and make an important contribution to the safety and high quality of production and logistics processes.
Applications are most frequently carried out on liquids and solids in process tanks, storage tanks or silos.

However, there are requirements in which level measurements are not feasible or attainable with conventional measurement technology due to the extreme boundary conditions or only possible with very high installation or maintenance costs. This is applicable, for example, in environments with high pressure or high temperatures or with aggressive or abrasive media.

Measuring Principle for level measurement

These difficult cases can only be solved with the help of radiometric measurement technology, which has been tried and tested for more than 70 years - a technology invented by Berthold. Externally applied gamma radiation penetrates thereby the measuring vessel. This is weakened depending on the vessel level. A detector located on the opposite side of the vessel measures the incoming radiation and can determine the level very accurately from the radiation attenuation. This level value is displayed either directly on site or integrated in a PLC or process control system. Learn more about how our level measurements work.

Radiation Interference Protection (XIP)

With this feature, welding checks do no longer falsify the measured value. The measured value is frozen until the radiation interference detection is over. A digital output signalizes the detection of radiation interference. All our level measurements are equipped with XIP.

Radiation Interference Discrimination (RID)

The patented method for Radiation Interference Discrimination, which occurs during welding tests with gamma radiation for example, makes our level measurement especially reliable and safe. The measurement continues without interruption, even if interfering radiation is present. Interference radiation is detected because of its different energy. The detector then switches to a second measuring channel and continues the measurement without interruption. All level measurements can be easily upgraded with the patented LB 470RID (Radiation Interference Discrimination) external radiation detection.
