Background
The radar level gauge belongs to a general radar level gauge, and is a measuring instrument based on a time travel principle, wherein radar waves run at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits high-frequency pulses which are transmitted in space at the speed of light, and when the pulses meet the surface of the material, the pulses are reflected back to be received by a receiver in the instrument and convert distance signals into level signals. The radar level gauge transmits very short microwave pulses of very low energy which are transmitted and received via the antenna system. The radar wave runs at the speed of light. The operating time can be converted into a fill level signal by means of electronic components, and finally the converted liquid level indication is displayed via a display screen. A special time extension method ensures stable and accurate measurement in a very short time.
