Results & Insights

Qatium runs your simulation as soon as you make a change in the network, e.g. closing a pipe. The time to results and insights is reduced to a minimum, allowing you to focus on your task at hand.

Visualize insights

Insights are visible directly on the main screen as soon as the model has finished running. Result layers are visible by default, allowing you to have an overview of pressure, flow and tank volume ranges and values. By hovering over the network elements, attributes and simulation results will be displayed. Clicking on the asset will display further insights. (This feature is currently only available for pipes) Qatium will display the timestep corresponding to your local time when the application loaded, for this page the timestep would be: . In order to visualize insights for another time-step, click, hold, and move the time-step cursor or click directly on the time-step you would like to visualize. You can play through the time-steps by clicking on the play button on the left side of the timeline. You can also move from one day to the next by clicking on the double right chevron button at the right hand side of the timeline. You can also move back to the previous by clicking on the double left chevron button  at the left hand side of the timeline. For more information on layer controls, we recommend reading through the Managing Elements and Layers section.  

Pressures

The pressure insights can be visualised as soon as a simulation has run, whether through the Pressure result layer or by hovering over the junctions. The pressure results are represented by colored hexagons, ranging from dark purple to light yellow. You can zoom to the highest and lowest pressure areas in the network by clicking on the pressure icon and selecting on the yellow and purple hexagons. For more information about the pressure layer controls, please see the section Managing elements and layers.  

Flows

The flow insights can be visualised as soon as a simulation has run. The flow is a value associated with pipes, to visualize the flow value hover over a pipe in your network: or click on a pipe: The flow can also be visualized thanks to the flow layer: For more information about the flow layer controls please see the section Managing elements and layers.  

Tank volumes

Tank volume insights can be visualised as soon as a simulation has run. Tank volume is a value associated with tanks, to visualize the tank volume value, hover over a tank.   Tank level information can also be visualized thanks to the Tank volume insight panel, located on the right hand side of the window.   For more information about the layer controls please see the section Managing elements and layers.  

Live SCADA, AMI and sensor data

Once you have live data feeding your Qatium model, sensor icons will populate the assets containing the sensors. Qatium will display a model accuracy grade and a model deviation for each sensor type implemented (currently flow, pressure and tank level). Both, model deviation and model accuracy, are indicators of the difference between the data received from the sensors and the data calculated by the model. They are both represented in percentages, the model deviation is also shown in raw value.  The model deviation is calculated for every timestep and for every variable available from: tank level, flow and pressure. The model deviation averages the differences between the sensor value and the model value, assigned to the same asset for each timestep. If there are no sensors for that variable the model deviation panel will not display that variable deviation. If there is no sensor value for a specific timestep. The goal is to have a model deviation as small as possible.with the minimum value being 0%.  The model accuracy is a daily percentage indicator calculated from every model deviation value of the day. It averages the available model deviations for the whole day, and transpose it making the higher the value the more accurate is the model. The goal is to have a model accuracy as high as possible with the maximum value being 100%. The accuracy grade is calculated from the different model deviation values, the higher the value the more accurate is the model. The model deviation values are calculated for each sensor type feeding your Qatium model. To visualize the model deviation values, you can click on the double arrow headed button on the right hand side of the window. The lower the model deviation, the closer are live data and simulated values. Deviations are calculated using last available sensor values and the simulation data. The deviation values will be shown in

• Green, for error below 10%
• Orange, if the error is between 10% and 20%
• Red, if the error is above 20%

By turning the toggle on, you will be able to visualise the locations where the model deviation are the biggest, hence where you might need to focus your calibration efforts. The locations will be circle in a large red halo if the deviation is greater than 20% and in a smaller orange halo is the deviation is comprised between 10% and 20% of the realtime value.
