Hi KRAZE4LV,
The purpose of the example is to create a simulated tank control environment that you can manipulate to be functional for your application. The example uses a random number generator, but you could easily change this to read data from a tank set up. The example displays a history of the inflow, level, and temperature in the three graphs for your record. There are also a set of parameters that you can set depending on what type of tank you have. Those parameters are the tank level, tank temperature, inflow rate, and inflow temperature.
Do you have specific questions about the functionality of one of the subVI's? The easiest way to learn about the different functionalities within each subVI is to use the Context Help, which you can display by pressing Ctrl+H. From here, you can hover over each function and see what its functionality is.
To explain a few of the more complicated subVI's, the Temperature VI takes in a set of metrics from the tank and performs an equation to find the new fluid temperture. Based on inputs to the boolean change VI, it will determine whether the output booleans are set to true or false which will in turn change the heat inflow rate. I hope this is partially helpful. Like I said, if you have any specific questions, those would be much easier to answer than to try to describe the functionality of the entire VI.
I hope this helps!
