Overview of Managed Meters

Managed meters are logical entities that are responsible for handling data for generating reports. These meters are used to calculate the consumption of energy, electricity, gas, water, and so on across various facilities, such as buildings, business complexes, and manufacturing plants. Using the Desigo CC Managed Meters you can configure the managed meters.

To configure a managed meter, you can associate APOGEE P2 and BACnet trend log objects as a metering point, which acts as a parameter to capture the meter readings. These trend log objects can also be configured as Managed Meter metering point and Source Meter metering point.
NOTE: SORIS and S7 trend log objects are not supported.

You must also provide the following information:

• Physical location of the meter in the facility.
• Logical (CNS) path of the meter in the management station.
• Purpose for installing the meter, such as calculating the consumption of electricity, water, oil, gas and so on.
• The units of measurement in which the meter will record values.
• The maximum meter reading.
• Offset and notification profiles.

You also have an option of associating a second metering point with a managed meter in the Source Meter expander in the Managed Meters application. This may be essential if the meter is used for dual purposes. For example, you have a cooling plant in which you want to calculate the quantum of water consumed, as well as calculate the total energy consumed in the cooling process. In this case, you can configure a managed meter so that you have one metering point that acts as a primary point to calculate the total quantum of water consumed by the cooling plant, and a second metering point that calculates the total amount of energy consumed by the plant.

Using this application, you can generate reports from historized data. This data includes the physical path of the object that is associated with the managed meter, the different views in which the meter is configured, the media units in which the meter records values, and the offset values.

There can be situations where a managed meter displays incorrect values, such as a negative value or a zero. You can correct this from the Manual Correction application.

Managed meters are covered by a license. The number of meters that you can create depends on the quantity provided by this license. If the number exceeds this quantity, the management station will run in Courtesy mode.
