The measurement is based on a laser scanner, which opto-electronically scans the measurement area. The real height of the pellet bed is calculated by subtracting the known distance from the steel belt from the measurements given by the laser scanner.
Measurement results are displayed in an informative and easy-to-use graphical user interface. The results are also available for the PCS through several communication methods. The system has been designed to be robust in harsh environments with excellent usability and it is delivered with easily replaceable spare parts.
