Level Measurement for the Process Industry | Overview

Berthold Technologies - the inventor of contactless level measurement

Level MeasurementLevel 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.

Radiation Interference Discrimination (RID)

The patented method for Radiation Interference Discrimination, e.g. welding tests with gamma radiation, makes our level measurement especially reliable and safe. The measurement continues without blockage, even against radiation. This is recognized because of its difference in energy. The detector then switches to a second measuring channel and continues the measurement in an error-free manner. All level measurements can easily upgraded with the patented 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.
