Introduction and Reminders
This page describes how the supply consumption algorithm functions based on recorded data.
For more information on importing records, you can refer to these pages:
- Site-by-site record entry
- Bulk record import
This algorithm enables the industrialized aggregation of recorded data from the main meters of all fluids, either for single-site or multi-site use.
Meter Configuration
Meters must be installed in your "Energy System" as main meters; sub-meters are not considered. In the asset file, this corresponds to the general meter being marked as true.
The meter must be real (see the "meter type" property).
Depending on the fluid and the unit of the meter, the "PCI Coefficient," "PCS Coefficient," "PTZ Coefficient," and "Conversion Coefficient" properties must be configured.
If they are not configured, default values are applied.
Consumption Normalization
- Water consumption is normalized in cubic meters (m³).
- Energy fluid consumption is normalized in kWh using the coefficients specified for each meter (or default values).
Consumption Linearization (Smoothing)
Consumption smoothing is carried out in two steps:
- Consumption is first calculated using the difference between two readings.
- Then, it is distributed between the two reading dates by dividing by the number of days separating the readings.
Thus, the consumption is smoothed over a daily time step, which will be applied for your daily, weekly, monthly, or yearly aggregations.
Example:
- Water reading taken on September 1, 2020, with an index of 5100 m³
- Water reading taken on September 29, 2020, with an index of 5380 m³
The consumption between the two readings is 280 m³ over 28 days: each day from September 2 to September 29, inclusive, has a consumption of 10 m³ (280 divided by 28).
The widget below compares the output via linearized natural gas supply consumption (in green), raw consumption (in blue), and non-linearized supply consumption (in black).
Consideration of Time Variations (i.e., History) in Meter Properties (PCI, PCS Coefficients, etc.)
When PCS, PCI, PTZ, and/or conversion coefficients are historicized to allow their values to vary over time, the change in value is considered for readings that start after the coefficient's historicization date.
For example, if the PTZ coefficient is set to 1 before January 1, 2020, and then to 1.05 from January 2, 2020, the coefficient value change will be applied to all raw consumption recorded on or after January 2, 2020.
Thus, consumption in kWh for the period from December 20, 2019, to February 13, 2020, will use the PTZ coefficient of 1.05, whereas consumption for the period from December 27, 2019, to January 1, 2020, will use the PTZ coefficient of 1.
Available Indicators
These indicators calculate the consumption from the main meters for each fluid, converted to kWh (or m³ for water). Consumption is also linearized.
Indicators are available for all fluids, both in PCI and PCS. They can be accessed by typing @supply in "Calculated Indicators" --> "Other Indicators."
Data Aggregation Method
Depending on the display period, data will be calculated as follows :
