Outstanding contactless level measurement solutions

Our gauges for contactless level measurement work non-contacting and non-intrusive. The continuous measurement of level uses a gamma radiation field that is emitted from a shielded source. There are two possibilities how this field is formed: The first possibility is to use a point source in combination with a rod detector. As an alternative option, a rod source can be used. As the radiation passes through the vessel, the liquid inside (e.g. oil or water) absorbs a proportion of it. At the opposite side of the vessel, the attenuation is measured by a highly sensitive detector. Since the measuring geometry and the type of radiation are constant, the attenuation will only be affected by a change in level. This method allows for a highly accurate level monitoring – irrespective of factors like temperature, viscosity, pressure or color. Our gauges for contactless level measurement are maintenance free and universally applicable on all kinds of vessels, without any modification of the plant.
