Select the Level Measuring Instrument widget from the Signals category.

In the Basic Configuration of the Level Measuring Instrument, assign a suitable label (title). The header can be displayed by selecting the check box. You can add a unit or suffix to the displayed value, which is shown after the value. If necessary, the width of the outer and inner circles can be adjusted.
As described above, you can also set whether the conditions and signal history should be displayed. You can also set whether the min, max, or zero line should be displayed or not.

To customize the colors, click the "Color" tab. The marking color is for the marking that is not covered by the wave. The wave marking is for the marking that is covered by the wave. You can also customize the wave color and the outer circle color.

To display multiple waves in an animation, go to the "Wave Animation" tab and set the Wave Count value to the number of waves you want to display in the animation. The animation time of a wave can also be adjusted.
The wave animation can be switched on and off via a digital signal. Use case example: If there are waves in a water application, this is visible in the widget.

Now you need to include a signal. To do this, click "Select Signal".

Clicking "Select Signal" opens the Select Entity window. You can add a previously created signal here.

Once you are satisfied with your configuration, you can save it.
