Berthold - Model LB 110 -Continuous Level Measurement System
Our continuous level measurement systems are used to monitor measuring ranges from a few millimeters up to several dozen meters. The radiometric level measurements operate with no contact and are nonintrusive and noninvasive. As the components do not come in contact with the measured material and do not include any moving parts, they do not experience wear or tear.
The non-contact level measurement is applicable for all kind of vessels, reactors, autoclaves, silos, and bunkers.
Based on the radiometric measuring principle, our level measurement systems are operated reliably and accurately under extreme process conditions. The measurement is carried out irrespective of the material temperature, pressures, or chemical properties. Internal obstructions such as agitators have no adverse effect on the measurement performance.
Continuous level measuring principle by Berthold!
Gamma radiation, emitted from a shielded source is attenuated as it passes through the vessel. This attenuation is measured by a highly sensitive detector, mounted at the opposite side of the vessel. As type of radiation and measuring geometry are constant the attenuation will only be affected by a change in level.
The continuous measurement of level uses a radiation field over the whole measuring range. If the level rises within the range of the radiation field, the attenuation becomes stronger and consequently the detector measures less radiation. In this manner, the level can be reliably monitored - irrespective of pressure, temperature, viscosity, color and all chemical properties.
There are different possibilities how a radiation field is formed. Either a rod detector or a rod source is used; sometimes it is most beneficial to use both in combination.
