Select how to display the Sensors
The Sensor Overview pages show side by side graphs of every sensor (configured in the Sensor Administration page). The main goal is to provide an at-a-glance indication if “patterned” variables lie 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.
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 grey band on each chart represents the pattern confidence bands computed from one month of historical sensor readings. A pattern corresponds to an expected behavior for the sensor. In OpenFlows WaterSight pattern confidence bands are computed for each sensor 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 the sensor values during the time period for which the bands were developed. A narrow band indicates that the sensor value has been relatively constant at that time of day for the time period (hour and day of week) for which the bands were developed.
Real raw values are re-sampled in every 15 minutes and 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.
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: Sensors will display in descending priority. Highest priority first. Sensors with a priority of 0 will not be displayed in the overview. The priority of each sensor is defined at the Sensors configuration, in the administration page.
Filters the grid of sensors to the ones containing the word fragment typed in (case-insensitive) and is also limited by the property selected under Measurement.
Filters the grid of sensors to the ones with matching measurement type.
See the sensors displayed by user defined groups. User defined groups or Tags are defined in the Sensor Configuration, under Administration. Please note that if no Tags are defined under sensors administration, this field does not appear.
Use the graphic toolbar to control the display of the charts shown on the sensor card.
Displays the Sensor Name and the color-coded status at the top. Click the Sensor Name to navigate the Sensor Details.
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.
The paginator at the bottom of the page divides the set of available sensors into "pages" and controls which page is being displayed. The number of charts per page can be picked from the "Charts per Page" dropdown.
Select the number of charts to as grid on the page
Note: Clicking the sensor card title navigates to the Sensor Detail of that specific sensor.
