DP Level with remote seals calculator
I put together this spreadsheet calculator that helps you configure differential pressure transmitters with remote seals. It also helps you set up the "scaled variable" so you can output in actual inches of product level. You can access the calculator at DP Level Calculators R8.xlsx
Also, be sure that the high side (high pressure side) of the transmitter is connected to the bottom of the vessel and the low side (low pressure side) is connected to the top of the vessel.
