Hallo,

I am new to the Modelica language and I hope some of the experts at this forum could give me an answer.

I am trying to make a new simple(r) OpenTank, one without heat-transfer & energy calculated of the ports on the tank. I am using the OpenTank  implemented in the Modelica Standard Library as background for my equations. I order to find make this new model I am looking for the "level" or "fluidLevel" equation in the tank, I do not see which equation this is. I have looked in "PartialLumpedVessel", but I cannot see identify it.
Can someone help me identify the equation?

Thank you in advance
