Why does the liquid level display “Insufficient Echo Energy”?

Answer: Possible causes:

Obstacles between the sensor and the target weaken reflected echo energy.

The sensor is not parallel to the target surface, leading to weak reflected echoes.

The measured target is not a flat solid surface or liquid surface.

The water level rises too high and submerges the probe.

Solutions:

Verify vertical/horizontal installation of the device; ensure no obvious obstructions on the radar probe.

Weak echoes in open environments may stem from antenna echo interference; increase RF transmit power.
