Abstract
Method and system for detecting a cleaning process in a radar level gauge configured to determine a fill level of a product contained in a tank, the radar level gauge comprising a transceiver configured to provide a transmit signal, S, to be propagated towards the product by a propagating device, to receive a reflected signal, S, resulting from a reflection of the transmit signal at a surface of the product, and to determine a fill level in the tank based on the received reflected signal, wherein the method comprises: at a measurement position above the fill level and a known distance from a reference position near a ceiling of the tank, determining a difference in signal amplitude between at least two different fill level measurements; and if the determined difference in signal amplitude exceeds a predetermined threshold value, determining that a cleaning process is ongoing in the tank.
