Calculating consumption

Updated over a year ago

Consumption on a meter

All measurements and consumption of a meter can be viewed on the Output tab on the meter's detail page.

Consumptions are simply the difference between two measurements of that meter. If the meter measures daily, then consumptions will be calculated on a daily basis.

If a meter has several channels which measure different utility types (heat, hot tapwater...), the user can select the channel he wants to consult the measurements or consumptions from. It is possible to filter the data for a specific start and end date, depending on the period the user wants to view.

Both measurements and consumption can be plotted on a graph.

When displaying the consumption graph, the user can define the period that is displayed and opt for a grouping of the data per time interval: all time, year, month, or day. Grouping on day can be a useful example to see short term anomalies (spikes or dips) in consumption. Hovering anywhere in the graph shows the user the exact value on that particular time.

There is also the option to compare the consumptions per month or per year, depending on the time interval selected. A bar chart will be displayed, showing the consumption of both periods that you are comparing.

It is possible to export measurements and consumptions of each meter to an Excel file. This can be done using the Export measurements / Export consumptions action on the meter list and detail pages.

Consumption on a service location, also known as service consumption

On each serviced location with an installed meter, the user can view the consumption on that address directly, without going to the meter detail page. This is basically the same graphical representation regarding consumptions that is visible on the meter detail page with the same display options.

Unit conversions supported

When measurement data is being processed in Zero Friction, automatic conversions are made if the unit of measurement configured for the corresponding channel in ZF is different than the one from the measurement.

For example, incoming measurement data is listed in Joules but the channel is configured with a unit of measurement of GJ. In this case the measurements will be automatically converted to GJ. The same applies to liters that will be automatically converted to m³ if the installed meter channel is measuring in m³. The same for readings in GWh which will be converted to kWh if the meter is configured in kWh.

Measurement units with conversion support

j, kj, Mj, Gj

Wh, kWh, MWh, GWh

l, m³

Conversions are also done for calculating the consumptions of a meter. When the installed meter has a channel that is configured in Joules, then consumption values will be automatically converted to GJ. The reason for this is that GJ is a more widespread accepted standard for showing consumptions values. The same applies for Wh or liter. Consumptions will be converted to kWh or m³.
