Web app example 1 - HTML5

There are three process units: a water source that empties into a tank, a tank with a variable-flow outlet valve, and a feedback controller. The controller controls the water level by sending a command to the valve. Each process unit is defined as a separate Javascript object, so units can be added to a model easily.
