Visualizing energy flows (Sankey)

An energy flow diagram uses arrows to represent energy flows, with the width of each arrow proportional to the flow rate. With this visual format, you can see how energy moves through your plant and where the largest flows occur.

Procedure

To define widget-specific display options, follow these steps:

1. Create a new widget of the type "Sankey" or edit an existing one.
2. Select a parameter which is visualized in the widget.
3. Click to define the required node.
   For each parameter, define a link from the source node to the destination node. This link represents the volume flow between the two points.
4. Assign a node name and select a color for the node.
5. You can also scale each link individually, allowing you to accurately represent the proportions of the arrows — even when using different units, such as kilowatts or liters.

Result

The Sankey diagram visualizes how the energy flows through the plant:

Visualizing the configured decimal places

Decimal places can be configured as follows:

• Tooltip

  • Incoming values and incoming values sum use the highest configured decimal places value of related parameters
  • Outgoing values and outgoing values sum use the highest configured decimal places value of related parameters
  • Difference values use the highest configured decimal places value of all related parameters (incoming and outgoing parameters)

• Value at Node

  • Absolute and percentage values use the highest configured decimal places value of all related parameters (incoming and outgoing parameters)

To hide decimal places, set the decimal places for all parameters to 0.
