Interface calculation

Seeking guidance on the calculation of the interface between two fluids in a closed container, using a differential pressure transmitter
1. Some users on Haiyou have calculated it; you need to go and look it up. Hard work will reward you. 2. Let me do the calculations and sell you the answer? Hehe, it’s great to have money. With money, I can be your person who prepares braised pork for you. You pay 2 parts of the cost, and I’ll sell you a trick that doesn’t require any calculations – how about that? :P
For example: one medium has a specific gravity of 1, while another medium has a specific gravity of 0.5. So, at 100%, the pressure difference is 1H (where H is the range height in meters), and at 0%, the pressure difference is 0.5H. The remaining pressure difference between 0% and 100% is easy to calculate; for example, it is 50% at 0.75H.
For details, see page P575 of the \"Manual for Automated Design of Process Monitoring and Control in Steel Enterprises\" – it is very detailed
Differential pressure = density of the medium below * height from the lower flange to the interface + density of the medium above * (difference in height between the upper and lower flanges – height from the lower flange to the interface). Draw a sketch and understand it step by step by relating the various elements together
It can’t be counted, right? Could you please explain in more detail?
