Level Widget
Summary
The level widget shows the latest value from a single tag, and renders it as a container/tank with upper and lower values. Indicators at 50% and 100% are added automatically, or additional markers can be specified by configuring a level widget’s display options.
Examples at a glance
Default view displaying the most recent value with minimum range set to zero and maximum set to 500.
Common applications
- Visualize real-time fill levels of coolant or lubricant reservoirs to ensure timely refills and prevent equipment wear.
- Display power storage levels for solar battery units to confirm energy availability throughout the day.
- Monitor material usage in batching systems by tracking hopper or feeder levels during production runs.
Configuration options
Hover over a widget and click the Configure Widget button (
) to control which tags to include and how data should be handled, such as defining the amount of data to display or scaling up subtle signals to make them easier to use. Once you have selected the tags to be shown, click ‘Next’ to configure data handling options using the properties below.
| Property | Options | Description |
|---|---|---|
| Range | Defines the upper and lower values of the widget. | |
| Minimum | Define the lower boundary value. | |
| Maximum | Define the upper boundary value. | |
| Metric | Enables data smoothing. Used to remove noise from data. | |
| Snapshot | No smoothing; Shows the most recent value. | |
| Maximum | Average the maximum values over a number of samples. | |
| Minimum | Average the lowest values over a number of samples. | |
| Refresh | Determines the frequency with which the widget will refresh the displayed data. Set longer refresh times for widgets that are not checked often. | |
| Auto | Sets the refresh rate automatically, based on the incoming signal. | |
| Set | Specify a refresh rate in seconds, minutes, or hours. | |
| Scale and Offset | Modify the raw data to either scale up the value by a multiplier, or offset the value by a fixed amount. Used to convert units (eg, watts to kW), or to correlate data streams with drastically different scales (eg, °F vs vibrations per second). | |
| Raw | No adjustment. | |
| Custom | Specify a scale factor and/or offset amount. |
Display options
Hover over a widget and click the Display Options button (
) to define conditions that change the way data is displayed, such as changing colors or showing text based on incoming data. Setting up multiple conditions can create widgets that are very dynamic, elevating critical information as data conditions change. See our tutorial on creating your first dashboard for an interface breakdown.
| Property | Description |
|---|---|
| Tag | Select the tag or tag state to configure from the list of incoming data. States will be shown in the format ‘StackName:TagName.State’ |
| Condition | Define the logic conditions under which your chosen settings will take effect relative to the Trigger Value. |
| Trigger Value | Define the threshold at which your chosen settings will take effect relative to the Condition setting. |
| Color | Select the fill color for the tank when the Condition and Trigger Value are met. |
