Overview
All sensors and assets (tanks, pumps) related information can be found and controlled under the Sensors tab, located in the side panel. To turn on/off the sensors on the map, please click in the visibility icon located on the top, under sensors tab. By default, sensors will be turned on.
Note: Sensors defined with priority 0 in the sensor configuration page (inside Admin) will never be displayed in the map page.
Status
In addition to this, on the top right of each sensor icon, a coloured circle is also displayed. The colour coding is based on time delay of the latest value found in the Sensor's database and depending also in its Communication frequency. More detail below:
| Category | Symbol | Description |
| Offline | Marked as offline by the administrator* | |
| No Data | (Now – Last InstantInDB) > 4 x MaxLagTime | |
| Partial data | (Now – Last InstantInDB) < 4 x MaxLagTime | |
| OK | (Now – Last InstantInDB) < 2 x MaxLagTime |
Where MaxLagTime is
15min + Sensor communication Frequency + Sensor Registration Frequency
Last Instant in DB corresponds to the last time step for which values were registered in the database for each given sensor. This time can be seen under Admin >> Sensors, by looking at Last Instant in DB column. Sensor communication frequency and registration frequency are also defined under Admin >> Sensors
* Sensors can be marked as Offline by the user administrator under Administration > Sensors. Offline sensors can represent sensors that have chronical problems (like no data or flat reading), well know by the utility, and for already a long period of time, and the issue is not expected to be solved soon. The majors advantages of having this category are:
- easier to distinguish between temporary problems and failures that the utility might not be totally aware and chronical problems that are already known by the utility for a long time
- make all the real time data ingestion process in the platform more reliable, mitigating degradation of performance or delays on the data pusher tool side.
Search
Clicking in the icon located on the sensor side panel to search for a specific sensor. Restricts the displayed sensors in the map and panel to the text fragment entered into the search field.
Filter
Clicking in icon located on the side panel to filter sensors. It is used to control the way the sensor list is displayed:
| Sort By | Description |
| Alphabetic | Sorts the list of sensors ascending in alphabetical order |
| Asset | Sorts the list of sensors by asset (pump, tank or other) |
| Status | Groups the list by status and sorts within groups in alphabetical order |
| Measurement | Groups the list of sensors by their measurement and sorts within the group in alphabetical order |
Filters:
| Status | Description |
| No data | Sensors report significant delay |
| Partial data | Sensor reporting moderate delay |
| OK | Sensor reporting within expected Delay |
More information above, under sensor status.
Measurement: Dropdown of measurement options to filter. The sensor measurement is configured under Sensor Configuration, under Administration.
Tag: see the sensors displayed by user defined groups. User defined groups or Tags are defined in the Sensor Configuration, under Administration.
Interacting with Sensors
Sensors are grouped in the map and in the side panel according to the following with the following type of assets:
| Tank | |
| |
Pump |
| |
Other |
Sensors associated with a tank or with a pump are represented by a tank or pump icon. Sensors that are not associated with either tanks or pumps fit under the others category and are represented by a wifi-symbol. Association of sensors to tanks or pumps is done in the administration > hydraulic structures >> Pumps, Tanks page.
Selecting a Tank
When clicking in a tank icon on the map or side panel, a chart with the level sensor reading for the previous 24 hours is shown together with more information on the side menu.
To exit this view or return to previous view, click on the close (x) icon located in the sensor chart or click on the back arrow located in the side panel.
Tank chart
Sensor level reading for the previous 24 hours is shown (black line with color coded circles) together with the expected patterns - grey bands (in case patterns are configured in Admin >> sensors). 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 in real time.
User can click in the expand button located on the top right of the graph for more detail. The chart will extend to full page with more options, such as: navigating in the time series history, create event button shortcut, changing pattern or time series-interval, adding model results or raw data, etc. More information in the sensor details help-page.
Schematic
Provides an at-a-glance indication in real time if tank levels are above or below minimum or maximum values defined (for the last 15 minutes average). If tank level is below the minimum value defined in the Tanks Configuration page, it will appear color-coded with a red color. If tank level is above the maximum value defined in the Tank Configuration page, it will appear color coded with an orange color. Average value is represented with dash line and corresponds to the expected tank level for the current time (obtained based on the percentile 50 of the level historical data).
Sensors
Level sensors associated with the tank. If a red warning is displayed along with the sensor name, this mean that there are active events associated to that sensor that need attention. Click on the sensor level to open the sensor detail. More information below under the section "Selecting a sensor".
Details 
By clicking in the details button the user will be redirected to the Sensor details page with more options, such as: navigating in the time series history, create event button shortcut, changing pattern or time series-interval, adding model results or raw data, etc. More information in the sensor details help-page.
Selecting a Pump
When clicking in a pump icon on the map or side panel, a chart with the pump flow-head curve for the last week is shown together with more information on the side menu.
Pump chart
Displays the pump head vs. flow curve, together with pump operating points (flow vs head), for the last week. Main goal is to provide an at-a-glance indication if pumps are operating near the expected range of values. Particularly useful to quickly spot pumps that are beginning to fail, or are operating in an inefficient manner.
Pump flows are obtained based on the pump flow sensor signal. Pump heads are calculated based on the suction signal and discharge signal, which can be either pressure or level signals. If the flow or discharge signals are not configured, the operating points will not be calculated. If the suction signal is not configured, the suction pressure will be assumed to be 0.
User can click in the expand button located on the top right of the graph for more detail. The chart will extend to full page with more options, such as: managing time series, enabling efficiency and power curve, etc . More information in the pump details help-page.
Average Performance
Average performance variables (flow, head, efficiency, power, best efficiency, efficiency deviation) for the period defined under Manage Series. If multiple series are selected, this displays the average across all series. Efficiency values are calculated based on pumps flow, head and power.
Invalid Efficiency points: percentage of points that were excluded from the analysis for the defined time period. Invalid points are excluded from the calculation of the pump efficiency and are also not displayed on the pump graphs. This includes for example cases:
- where the pump SCADA power is 0 and the flow & head are non-zero (meaning efficiency calculation would be infinity)
- SCADA power is unrealistically low or the flow unrealistically high, which would mean an efficiency greater than 100%
Realtime Performance
Real time values for each pump: flow, head, efficiency, power and speed. Efficiency values are calculated based on pumps flow, head and power.
Sensors
Sensors associated to the pump (defined in the administration). If a red warning is displayed along with the sensor name, this mean that there are active events associated to that sensor that need attention. Clicking directly on the name of each sensor will directly redirect the user to the sensor detail (see "Selecting a Sensor" section below)
Details 
By clicking in the details button the user will be redirected to the pump details page with more options, such as: navigating in the time series history, create event button shortcut, changing pattern or time series-interval, adding model results or raw data, etc. More information in the pump details page.
Selecting other Sensor (neither pump or tank)
When clicking in a sensor (wi-fi symbol) from the map or in a sensor on the side panel (located under the assets tank, pump or others), a chart with sensor reading for the previous 24 hours is shown together with more information on the side menu.
To exit this view or return to previous view, click on the close (x) icon located in the sensor chart or click on the back arrow located in the side panel.
Sensor chart
Sensor reading for the previous 24 hours is shown (black line with color coded circles) together with the expected patterns - grey bands (in case patterns are configured in Admin >> sensors). 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.
User can click in the expand button located on the top right of the graph for more detail. The chart will extend to full page with more options, such as: navigating in the time series history, create event button shortcut, changing pattern or time series-interval, adding model results or raw data, etc. More information in the sensor details help-page.
