I would like to ask about the measurement of liquid ammonia tank level

In our plant, when the pump injects liquid ammonia into the tank, the liquid level indicator for that tank rises very high suddenly, and then it gradually returns to the correct level over some time. Currently, a EJA110A transmitter is being used to measure the differential pressure in order to determine the liquid level; there is no insulation on the sampling tube, and the outdoor temperature is currently around 15 degrees. I previously replaced it with a level gauge of the same model; it worked fine for about a week before stopping working again. Please help analyze the reason and suggest how to solve this issue.

Fluctuations are normal; this is different from other liquids

What are the dimensions of the groove? Consider a guided-wave radar level gauge?

Should it be measured using a double-flange differential pressure transmitter?
