For this problem you could use your own model. Try to look at the fluid example called tank controller. Or you could look at my model for tank controller by messaging me at muhammadfadli27@gmail.com ( i am currently working to build a Water Dispenser including the thermal condition)

I want to ask about how could i deploy my current model without using emscripten because after i ask, emscripten is currently not working for the latest OpenModelica. So how could i deploy my model to a wesbite ?
