Signal Strength of Guided-wave Radar Level Instrument

The following graph shows the signal strength received by a guided-wave radar (GWR) level instrument over time:

Explain how the graph will change if:

1. The liquid level increases

2. The dielectric constant (ε) of the liquid decreases

3. The density of the liquid decreases (assuming constant ε)

4. A liquid-liquid interface consisting of two liquids with different densities is introduced into the vessel

5. Also, explain what UNZ refers to (the Upper Null Zone).

6. Describe a practical reason for configuring a radar transmitter to have an upper null zone, and how this differs from a radar instrument’s transition zones.

7. Explain why the timing of both the echo pulse and the end-of-probe pulse will shift as liquid level changes in this system.
