The Link Flow tab allows you to assign field measured flow data to select links across the distribution system. During the calibration simulation, the properties of the system will be altered in order to generate a correlation between the actual field data and the simulation results. When a correlation is establish within the parameters specified (link flows included), the model will reach a state of calibration with results being written to the Run Summary tab.

Main Menu


Mode - Choose a mode (Steady State, Fire Flow, or Extended Period) for Calibrator.

Run - Go to Run to Start and Stop the trial. You can also choose Options.... to view the Calibration Options dialog box: 

Help - Click to go to ContentsIndex, or About Calibrator to find more information on Calibrator.

Link ID

Input the link ID where flow data has been measured.

Time

Modes: EPS only

Insert the time associated to the target flow measurement.

Observed

Input the user-specified target flow to be met for the corresponding link ID.

Simulated

Displays the flow predicted based on the solution obtained for the calculated model parameters (i.e., pipe roughness, junction demand and pipe status).

% Diff

Displays the percent difference between the observed and simulated flows.

Input Data Buttons

The Input Data buttons located on the right side of the dialog box allows you to input and edit data into the data fields as well as to analyze the data once it is entered.

Insert ID

This button allows you to select an element ID by using the map to select the element directly from the map display.

Update ID

This button allows you to update an element ID assigned to the current grouping via graphical selection from the map display.

Select Time

This button allows you to select with the time slider display.

Clear All

This button will remove each ID from the current dialog box.

Load

Use this button to load a selection set of ID's into the table.

Save

Use this option to save the ID's in the table as a selection set.
