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.sub.T, to be propagated towards the product by a propagating device, to receive a reflected signal, S.sub.R, 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.

A waveguide arrangement for transmitting microwaves, and for measuring a limit level or a filling level, is provided, the waveguide arrangement for transmitting microwaves including a waveguide tube having a rectangular or elliptical inner cavity and an outer wall; and a jacket, an inner wall of which corresponds at least in sections with a shape of the outer wall of the waveguide tube.

The innovation described herein generally pertains to a system and method related a wireless remote monitoring system for a tank, wherein the wireless monitoring system is incorporated into or coupled to a lid for the tank. The wireless remote monitoring system for the tank can include a cover system that includes a lid mountable on a corresponding tank, the lid comprising a space sized and shaped for receiving the wireless remote monitoring system therein, wherein the wireless remote monitoring system is operatively coupled to a sensor.

A system for determining a fluid level includes a front end and a measurement probe. The measurement probe receives a pulse from the front end and returns a partially reflected pulse and a fully reflected pulse to the front end. The partially reflected pulse is evaluated to determine a liquid level within a tank that includes the measurement probe. The measurement probe includes a conductive trace configuration to provide a time delay to prevent pulse build up.
