Sometimes in industrial processes it is necessary to fill or empty the reservoirs to a certain level, so a system for detecting the desired point from the reservoir level is needed to inform the operator or the electronic system when the material reaches the desired level.
One of the most accurate and fastest instruments in this area is gamma dot scanner.
The gamma source is shielded, and the detector is installed as the shape in the desired height from the reservoir.
When the material level inside the reservoir reaches the location of the source and detector, the radiation will be significantly diminished.
This strong and sudden weakening is measured by the detector installed on the opposite side of the enclosure, and immediately the interrupting order is sent to the operator or the electronic system.
