Select how to display the Zones
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.
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 to show last 6 hours, last 12 hours, last 2 days, last three days or last week. To change these configurations please click in the configurations button (inside graphic tools) located on the top right.
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.
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.
Real (re-sampled) values are represented as a black, red or orange circles. 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.
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.
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.
Filters the grid of zones to the ones containing the word fragment typed in (case-insensitive).
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.
Use the graphic toolbar to control the display of the charts shown on the zone card.
Displays the Sensor Name and the color-coded status at the top. Click the Zone Name to navigate the Zone Details.
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.
