If you search this forum for "pumps valves pipes" you'll find several threads talking about this. The Datalogging and Supervisory Control module has some of this.
You can also import pictures onto existing controls like booleans (for valves). Here are some notes for LabView 6 or 7.
1. Find or create an image you want to use. You can use Google image search to find free stuff on the web.
2. Using any graphics editing program (like Paint for BMP files), open the image, select it, and copy it to the clipboard.
3. In LabView, right-click on the control and select Advanced >> Customize. The Control Editor window will pop-up. If Customize is greyed-out, you already have the Control Editor open. Close it and try again.
4. In the Control Editor, click on the wrench b
utton on the toolbar to change it to the tweezers.
5. Right-click on the control and select Import Picture. If Import Picture is greyed-out, you don't have an image in the clipboard. Go back to step 2.
6. You may want a different picture for the False state of a boolean. In the Control Editor, right-click on the control and select Picture Item, then select the next picture. Go back to step 2 to copy the next image to the clipboard, the repeat step 5 to import it.
7. Close the Control Editor. Save the control as prompted, and replace the original control as prompted.
