Radar level gauging with power-dependent number of measurement operations

A radar level gauge system, for determining a filling level of a product in a tank, the radar level gauge system comprising:

• a transceiver for generating, transmitting and receiving electromagnetic signals;
• a signal propagation arrangement coupled to the transceiver for propagating an electromagnetic transmit signal towards a surface of the product and returning to the transceiver an electromagnetic reflection signal resulting from reflection of the transmit signal at the surface of the product;
• power monitoring circuitry for determining a measure indicative of a presently available power for operation of the radar level gauge system;
• and
• processing circuitry coupled to the transceiver and to the power monitoring circuitry, and configured to:
• acquire the measure indicative of a presently available power for operation of the radar level gauge system from the power monitoring circuitry;
• perform a set of measurement operations including a number of measurement operations being dependent on the presently available power for operation of the radar level gauge system, each measurement operation including controlling the transceiver to generate and transmit an electromagnetic transmit signal, to receive an electromagnetic reflection signal resulting from reflection of the transmit signal at a surface of the product, and to form a measurement signal indicative of a timing relation between the transmit signal and the reflection signal;
• and
• determine the filling level based on a set of measurement signals including the measurement signal formed in each measurement operation in the set of measurement operations.
