The 3DLevelScanner employs an array of three antennas to transmit low frequency pulses and to receive their echoes from the contents of the silo, bin or other container. These three antennas measure not only the time/distance of each echo but also its direction. The device's Digital Signal Processor samples and analyzes the received signals to provide very accurate measurements of the level and volume of the stored contents, and generates a 3D representation of actual allocation of product within the container for display on remote computer screens. This unique device measures practically any kind of material stored in a great variety of containers, including silos, large open bins, bulk solid storage rooms, stockpiles and warehouses. It maps build-up loads and other irregularities that randomly form over time, offering solutions for this and many other previously inaccessible challenging applications.
