FIELD: measuring equipment.
SUBSTANCE: invention relates to a radar level gauge system. System comprises a signal propagation device, a microwave signal source connected to the signal propagation device, a microwave signal source controller connected to said source, a mixer connected to the microwave signal source and to the signal propagation device, a sampler connected to the mixer, and processing circuitry connected to the mixer. Microwave signal source controller and sampler are configured to be controlled independently of each other, and so that the duration of each of the frequency steps of the measurement scan can be set to be different from the time interval between consecutive samples obtained in the sampling process.
EFFECT: accurate determination of the level of filling with a significantly limited supply of energy and/or power.
