Graphs
On the top right of the page, select for which elements to display graphs:
| Sensor Overview | |
| Zones Overview (this page) | |
| Large Customers Overview |
Zone overview provides a dashboard for at-a-glance indication if the current zone flow lies within the expected range of values. Particularly useful to quickly spot any anomalies (that can represent bursts, leaks, tank overflows, pressure problems, maintenance works, etc) in real time, inside a specific zone.
Zone Graphs
Zones should correspond to isolated areas of the system, surrounded by closed valves and where all inflows and outflows (if exist) must be measured. Zones can include for example DMA (District Metered Areas), pressure zones or operational zones. The configuration of the inflow and outflow sensors as well as tanks levels that may exist inside the zone are configured in the Zones configuration page (at the administration level) by the user.
By default up to 6 graphs are displaying chart readings of the past 24 hours and a forecast of 6 hours. The time range period considered for all graphs can be changed by pressing the calendar icon button .
The number of zones to be displayed simultaneously is limited by page - the user has the option to navigate to the following pages to see the remaining zones or search for a specific one. The current page and the number of charts that are displayed on a page are identified at the top left of the page.
Influence of Large Customers on the Zones Flow
Comparing the zone flow with the large customer consumption can help utilities discard possible leaks or bursts that can be in fact large customer consumptions, avoiding generation false alerts. More information here.
Pattern
The grey band on each chart represents the pattern confidence bands computed from one month of historical sensor readings within the zone. A pattern corresponds to an expected behavior for the zone. In OpenFlows WaterSight pattern bands are computed for each zone using advanced data analytics (statistic equations together with machine learning techniques to remove outliers or bad data). For these calculations several considerations such as the data history for each specific sensor as well as the distinction between week-day and weekend are taking into consideration.
A wide grey band indicates that there were large variations in flow during the time period for which the bands were developed. A narrow band indicates that the flow has been relatively constant at that time of day for the time period (hour and day of week) for which the bands were developed. If there is not enough historical data to compute the pattern confidence bands an informative message is displayed, and only real (re-sampled) values are shown. Clicking on this message removes the message.
Patterns can be customized by the user in the Administration page, under Settings > Pattern
Real time data
Real (re-sampled) values are represented as a black, red or orange circles. Those real (re-sampled) values are calculated based on the final balance between all inflows and outflows (plus accounting for storage inside the zone if exists). Whenever real data (re-sampled) goes outside the pattern confidence bands (above percentile 95 or below percentile 5 of the pattern), an outlier is identified and the value is color coded with a red circle.
Note: Zones will display in descending priority, highest priority first. Zones with a priority of 0 will not be displayed in the overview. The priority of each zone is defined at the Zones Configuration, in the administration page.
Estimated data
If estimating data option is set to yes, every time one of the sensors fails or every time a meter failure event is registered at the sensor level, the software will automatically estimate the final zone flow. Estimated data will be represented in the graph with empty circles. Please note that the gap filling option only exists at the zone level, this means that in the sensor graph this problem (missing data or gaps) will always be noted so the user can be always aware of the real issues at the sensor level. Please also note that zone events/alerts are never generated based on estimated data. The option to use gap filling (estimating data) or not is done in the zone administration page.
Search
Filters the grid of zones to the ones containing the word fragment typed in (case-insensitive).
Tags
See the zones displayed by user defined groups. User defined groups or Tags are defined in the Zone Configuration, under Administration. Please note that if no Tags are defined under zones administration, this field does not appear.
Calendar Icon - select different time periods
Press calendar icon as well as the left and right arrows to select different periods for the overview time series that are displayed, including any historical period. Once selected, all the overview graph dates will updated accordingly with the selection.
Graphic Tools
Use the graphic toolbar to control the display of the charts shown on the zone card, with the possibility to add additional information:
| Entry | Description |
|
Turn on/off: - Legend of the graphs - Signal data - Events highlighted in the graphs (with the additional flexibility to display only active events or all events) - Statistics (or patterns) - Current time marker |
|
|
Turn on/off "full y-Range option" in graphs and define the time period for the graphs (last 6 hours, last 12 hours, last day, last two days, last three days, last week) |
|
| Download data that is being displayed on graphs (PNG or CSV format) | |

More graph configurations: spike lines, data tooltip and font size.

Zone Card/Graph
Displays the Sensor Name and the color-coded status at the top. Click the Zone Name to navigate the Zone Details.
Cycle
Located at the bottom left corner of the page, it allows to specify rate at which pages are automatically changed. Dropdown is displayed when more than 1 single page is available. Cycling can be deactivated or set to one of the offered rates.
Paginator
The paginator at the bottom of the page divides the set of available zones into "pages" and controls which page is being displayed. The number of charts per page can be picked from the "Charts per Page" dropdown.
Charts per Page
At the bottom right corner of the page, the user can select the number of charts to as grid on the page
| Entry | Grid Size |
| 6 charts per Page | 3 x 2 |
| 9 charts per Page | 3 x 3 |
| 12 charts per Page | 4 x 3 |
| 15 charts per Page | 5 x 3 |
