How does the gasifier quench chamber liquid level transmitter correspond to the on-site liquid level gauge?

1. The calculated liquid level of the gasifier quench chamber liquid level transmitter does not correspond to the on-site liquid level gauge. According to the calculated value of the liquid level transmitter, it is higher and the on-site low value should be normal. But how to correct it? 2. Among the three double-flange liquid level transmitters, one lower port is at a relatively high position, and the other two lower ports are at the same and lower position. Where should the zero point be selected? 3. Our current system load is 68%, and the on-site replica liquid level gauge has dropped to 1.25m. Basically, for every liter of 5% load, the liquid level drops by about 10CM. According to the replica liquid level, it is close to the trip value of 2.1m. How can we confirm the actual liquid level in the furnace? How low can this level go without causing a safety issue? 4. A teacher from East China University of Science and Technology suggested adding a compensation formula to correct the displayed value of the liquid level transmitter. Has anyone corrected it? Need it?
Can you talk about the selection of base points for different liquid level gauges on the same equipment? What are the general rules for majors? In addition, compared to the gasification furnace quench chamber, the water phase is actually a mixture of gas (process gas) and liquid (water). The density of the water phase is definitely different from that of pure water circulation. How big is the difference between the actual liquid level in the furnace and the indication of the on-site liquid level meter outside the furnace?
This is very simple. I think we just need to see if their differences remain unchanged. If the differences are consistent within the range, the appropriate zero point can be reselected.
Correction using correction data from East China University of Science and Technology
There is a correction formula, but it still needs to be corrected.
