The pulse radar level gauge is a non-contact liquid level measurement instrument based on the time travel principle.
Working principle: The pulse radar level gauge emits extremely short microwave pulses with very low energy. These pulses are transmitted through the antenna system and conducted along the cable or rod probe. When the pulse encounters the material surface, it is reflected back and received by the receiver inside the instrument. The electronic components calculate the distance between the material surface and the probe based on the pulse travel time, and then determine the liquid level height.
