Level Measurement for the Process Industry | Overview
Berthold Technologies - the inventor of contactless level measurement
Level Measurement
Level measurements and the detection of level limits are fundamental in the process industry to ensure safe and high quality production in the 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.
These difficult cases can only be solved with the help of radiometric measurement technology, which has been tried and tested for more than 65 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.
Berthold Technologies is unique in the specialization in contactless measurements in the process industry worldwide. This guarantees you expert and skilled support ranging from advice on engineering through to the operation of the system.
Your advantages in level measurement with Berthold: |
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.
Radiation Interference Protection (XIP)
With this feature, welding checks do no longer interfere 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.
