WaterSight - Sensors

Product(s): WaterSight
Version(s): 10.00.
Area: Documentation

Overview

Administration page used to import sensors data (SCADA sensors or data loggers installed in the system) and sensors characteristics into WaterSight. Sensors types available to upload include the following types: flow, pressure, level, pump power and pump status.

It is possible to import sensors information through a configuration excel file (template file available for download in the Digital Twin Setup page) or to manually add a sensor and its characteristics. After uploading sensor information, it is also possible to edit, delete or copy information, using the available buttons located above the table. 

Note: To enable the Copy, Edit and Remove options, please select a sensor first (row in the table). When clicking in a specific sensor (table row) the fields available for editing will appear below the sensor configuration table.

The more actions button includes:

  • Purge: clicking purge when a sensor (row) is already selected will delete all the data/history for that specific sensor. If the On-Premise tools (On-Site Coordinator and SCADA Pusher) are working, the sensor should be automatically re-uploaded with the historical data after some minutes;
  • Purge all: this option deletes all the data/history for all sensors. If the On-Premise tools are working, sensors should be automatically re-uploaded with the historical data after several minutes;
  • Delete all: this option deletes not only the data but also all sensor elements (together with all properties defined) from the application. 

In order to have sensors transmitting real time data into WaterSight, it is required that:

  • The user completes the sensors configuration table (below) - at least all minimum required fields; 
  • The On-Premise Tools are correctly installed and configured in a machine that has direct access to the sensors data and is running 24/7. 

Sensor Configuration Table

Note: Minimum required fields are marked with an asterisk.

Column Description
ID/Tag*

Required field. Unique name in the database for each sensor. Please just consider flow, pressure, level, pump power or pump status types. 

Name The name which will be displayed in the application. If empty tag name will be used.
Type*

Required field. Parameter of the signal in the database/source. Options are flow, level, pressure, power or status. 

Units* Required field. Units of the parameter in the database.
Communication Frequency*

Required field. Communication or transmit frequency. The typical time interval in minutes in which the collected/read data is sent to the database (eg: 60 = in every 60 minutes data is send to the database).

Note: most SCADA sensors have low communication frequencies (communicate every minute or every 5 minutes for example) but some sensors (like for example dataloggers, AMI systems,, IOT devices) may communicate with the data source only once or twice a day but download data covering multiple time steps at one time

Registration Frequency*

Required field. Minimum read frequency. The time in minutes interval in which at least one data point is expected to be registered in the database (E.G 15 means at least one data point is expected every 15 minutes)

Note: This is different from the communication frequency. One sensor may only communicate once a day, but the registration frequency may be every 5 minutes for example (this means that data gets into the data source only once a day, but when it arrives there is data for all the day in every 5 minutes time step)

Timezone*  Required field. Time offset from UTC given in HH.mm. (example -05:00 or 05:00). 
Longitude* Required field. Longitude related to sensor location as a decimal value, referred to the same coordinates system as the uploaded hydraulic model. For more information on the model coordinates system, click here
Latitude* Required field. Latitude related to sensor location as a decimal value, referred to the same coordinates system as the uploaded hydraulic model. For more information on the model coordinates system, click here
Reference Elevation Elevation of Sensor above datum (usually mean sea level). Only required for pump pressure data (in order to calculate the head).
Last Instant in DB Once a connection between WaterSight and Sensors data source is established, this column will display the last instant available in the database.
Priority

The priority when displaying in the sensor overview. Note that a priority of 0 means that the sensor will not be included in the Sensor Overview

Tags (User defined groups)

It is possible to insert tags (or user defined groups) for each sensor, by directly filling the Tags column in the Sensors Configuration Template or by directly clicking in a row in the Sensors table, then clicking Edit    and then filling the Tags section below the table. 

Once tags are defined, those will be available in the Network Monitoring pages, so that is easier to search and find specific sensors of interest. Below some examples of groups that may be relevant:

  • grouping sensors by zones
  • grouping sensors by towns
  • grouping sensors by vertical assets (pumps, tanks, PRV, etc)
  • grouping sensors by critical and non-critical
  • etc, etc
