In Zero Friction several types of models/brands of meters can be configured. These are the general templates for each model of meter that your organisation will be using on the serviced locations.

Each meter model has it's own channel template(s) where the characteristics of this type of meter are stored. Characteristics of a meter model are the frequency of the measurements (hourly, daily, weekly...), the metering method (volume, energy...), the utiltiy type (hot tapwater, cooling, heat...), the direction (off-take, injection, not applicable), the unit of measurement (m³, GJ, Kwh...) and time of use (day, night). These templates have to be set up first by the user in order to be able to add individual meters to a serviced location.

A meter can be installed on a location: - Using the Install a meter action on the location and meter detail pages. - Directly after its creation in the Location wizard.

The user has to provide a serial number, select a meter model, the metertype (individual meter, aggregating meter, communal meter, external meter) and the creation date of the meter. The installation date of the meter on the serviced location has to be supplied by the user. The installation date is always equal or more recent than the creation date of the meter. It is possible to add a meter tag as a hint for the user to know what meter it is or where it is on the serviced location (for example: meter in garage).

The user has to select the channels that you want to retrieve information from and their invidiual settings. Ideally a preconfigured template can be selected and no further adjustments are needed.

It is possible to add a meter to a property group. This can be the case for a meter that is the main meter for a building. This can be interesting when you want to calculate losses of heat for example. Using the consumption from the main meter of the property and subtracting the consumptions of the invididual meters of its locations will give you an indication of the loss.

On the property detail page you can directly add a meter for that property. This can be a new meter or an already existing meter.

Meters installed on a serviced location are measuring one specific address. This address can be part of a property group.

Meters installed on a property group are actually main meters or aggregating meters for the whole building or project. These property meters are not used on invidual contracts of tenants, but are more for evaluation purposes and more of a control measure for figuring out losses in the building.

A meter can be removed by going to the meter detail page and use the Uninstall action. An uninstall date has to be provided. From the moment a meter is uninstalled, no more meter readings will be seen for this meter on that serviced location.

It is possible to reconfigure an installed meter. This could be necessary if a misconfiguration has been made when installing the meter. For example: the unit of measurement should be in kWh instead of GJ. On the meter detail page, the user can reconfigure the meter, adjusting the channels and its parameters to the correct settings. Here it is important to pay attention to the reconfiguration date. This is the date from which the changes will apply.

In Zero Friction it's possible to add a submeter to an installed meter. This way a user can work with a parent-child relation. This can be usefull when a separate meter exists for, what would otherwise be, a channel of one single meter. Adding a submeter can be done on the meter detail page of the parent meter. The submeter has to be an existing meter in Zero Friction. If it doesn't exist yet, the user has to create the meter first.

Zero Friction supports 4 different meter types, each having a different purpose.
