Abstract: A radar sensor for sensing the level of a product or the topology of the surface of a product having a continuously operated clock that closes a power supply line to the processor at a predetermined time to activate the processor. Thereupon, the processor controls the switching arrangement to activate the radar chip.

Abstract: A multi-dimensional measuring fill level radar with a processor, a programmable logic gate, one or more radar chips and a power supply and a method of detecting a level or a topology of a surface of a product by a fill level radar including starting a processor, performing a measurement cycle, when sufficient energy has been collected, by starting a programmable logic gate and launching one or more radar chips to perform a radar measurement sequence, switching off the radar chips, calculating the topology or fill level by the programmable logic gate and/or processor when sufficient energy has been collected, switching off the programmable logic gate, and switching off the processor.

Abstract: A method of adjusting a quantization accuracy of a fill level radar for detecting a fill level of a container is provided, the method including the steps of: acquiring amplitude values of an echo curve of the fill level radar by an analog-to-digital converter (ADC); determining a first amplitude value of a first echo having a highest amplitude or a highest local amplitude maximum of the echo curve; determining a second amplitude value of a second echo having a lowest local amplitude maximum of the echo curve; setting an adjusted quantization accuracy as a function of a quotient of the first amplitude value and the second amplitude value; and determining the fill level of the container with the adjusted quantization accuracy. A field device including a fill level radar and/or an ultrasonic measuring device configured to perform the method is also provided.
