The Meters App allows you to view traditional data from utility meters into various quantities related to instantaneous and cumulative consumption as well as cost and CO2. These quantities can be based on a pulse output from a traditional meter, or an energy meter based on CT-only measurements. You can also use the App to transform existing data channels or meter app data channels using a variety of analytic operations.
The resulting data channels created by the Meters can be used on your other Dashboards for display as Basic Widgets or Chart Widgets, and will allow you to set thresholds and alerts.
Creating a Meter Group
First you'll need to click on the 'Meters' dropdown and select 'Add Meter Group'.
After naming the group, click 'Create Meter Group' to create your new Dashboard.
To begin, first click on the 'Add Meter' button in the top right of the screen. Next, select which Meter type you'd like to create.
Current Transformer Based Meters
A meter based on CT measurements will use one or more data channel based on CTs to calculate instantaneous power readings (kW), total energy consumption (kWh), cost ($), and CO2 (mtCO2). The meter will calculate these quantities based on whether the circuit is single phases, 3 phase, or split phase and how many of those phases are monitored by CTs.
Pulse Based Meters
A meter based on the pulse output of a meter will a pulse data channel to calculate a variety of consumption and cost calculations depending on meter type. The meter will calculate these quantities based on the pulse constant, which refers to the amount of energy/water/gas consumed per pulse output. When keeping track of the meter readings based on a meter with a previous value, enter the initial value in the Initial Offset field. You'll also be able to update this reading at a later time.
When creating a pulse based meter, you'll be able to select the type of meter, as shown below, and then enter the pulse constant. The Unit Cost and Initial Readings field are not required.
You can also transform one or more data channels through the use of the following operations: sum, average, difference, product, and quotient. After selecting the desired operation and an offset to apply to the result, if applicable, simply select the relevant data channels for which you'd like to apply the operation.
If you need to update a meter reading after the initial setup of your Meter, click on the 'Update Readings' button in the top right of the Meters App Dashboard. You will then be able to enter a reading that was taken at a specific date and time, which you can enter. The Meters App will update your meter readings appropriately.
