Step-by-step Guide

Once a connection is established between live data and a network, the data can be used to perform a run, and the results can be graphed to see how the system performed in real-time.

To perform a run with live data points in a network:

  1. Create a new run with the live data connected to the network, OR use an existing one. In this example, BridgeTown Base already exists in the Run Group.
  2. Double-click to open BridgeTown Base.
  3. In the Schedule Hydraulic Run dialog box, update the network and control to their latest versions.
  4. In the Run Parameters group box, change the Start to 6 December 2022 by clicking on each section of the field and typing the day and month.
  5. Adjust the End to 8 December 2022.

The Schedule Hydraulic Run dialog box configured, with the network, control, and demand diagram activated, the Start and End dates entered, and a Parameter Setup Message written.

These dates match those in the live data files connected to the network.

  1. Click Save.
  2. Click Re-Run.
  3. Open the results by clicking and dragging the BridgeTown run onto the GeoPlan.

To graph the results:

  1. Select the Graph tool.
  2. Select a network object with live data attached to it. In this example, hydrant 311362 is selected.
  3. With the Select what to graph for dialog box open, click and drag the Live Data Configuration to the Live Data Configuration group box.
  4. Select Pressure (m).
  5. Enable Add Live Data.

Hydrant 311362 selected in the network, with the Select what to graph for dialog box configured for this exercise.

  1. Click OK.
  2. In the notification that follows, click OK.

A graph opens, showing the pressure as a blue line and the live data as a green line. There is a pressure drop in the live data around 7 a.m. If the time you run the model for exceeds the time of the live data, the live data would simply stop at that point. However, in this example, the live data shows the pressure dropping to 0. That means that somewhere in the live data files or through your telemetry system, something has happened in the network to cause a drop in pressure. For example, a burst pipe or telemetry system drop-off may have occurred.

Graph displaying a pressure drop in the live data around 7 a.m.

  1. You can graph other objects with the available live data to see similar results that also show the rapid drop in pressure occurring at around 7 a.m.
