The liquid level in the ammonia tank is low at night and rises during the day, reaching around 20 centimeters. What could be the reason for this?

The boiling point of ammonia, or thermal expansion and contraction – I’d like some advice
The approximate diameter and height of the tank need to be provided, so as to determine the percentage variation within 20 cm. Is this error detected through magnetic level gauges on site, or via some kind of sensor signal? Is the transmission cable shielded?
There is a high likelihood of thermal expansion and contraction. Furthermore, does the level gauge transmit signals based on pressure changes? If so, pressure will also fluctuate due to sunlight exposure...
Please provide a detailed introduction to the actual relevant situation :)\.
Materials expand when heated and contract when cooled, with significant changes in density at different temperatures.
Is it a level gauge with two diaphragms filled with silicone oil? That’s the situation here; many tanks are in the same condition. It is suspected that the issue is caused by uneven heating of the capillaries or diaphragms on the high and low pressure sides, for example due to sunlight exposure
