Abstract

A level measurement device for measuring a level (L) of a product (1), in particular a product contained in a container (5), comprising: mounting means (3) for mounting said measurement device at a measurement site, an antenna (9) comprising a dielectric antenna element (11) for transmitting microwave signals (S) towards the product (1) and/or for receiving echo signals (R) resulting from reflections of the transmitted microwave signals, and measurement electronics (15) for determining the level (L) of the product (1) based on a transit time needed for the microwave signals to travel to a surface of the product (1) and of their echo signals to return to the device, is described allowing to prevent deposits to build up, which may eventually impair transmission and/or reception of the signals. To this extent, the measurement device according to the invention comprises a cap (25) covering said dielectric antenna element (11) and cleaning means (27) for cleaning said cap (25) are foreseen, which cause said cap (23) to vibrate when they are activated.
