Hi wdenham,
Well, it's always a challenge to customize the controls in LabVIEW
exactly to what you want. It often takes a lot of patience and
creativity and good picture editor skills. However, I wanted to show
you that it indeed IS possible to do such a thing in LabVIEW, so I
created a version of a round tank control:

This might not be exactly what you wanted, so I will recommend you to
further customize it or maybe start from scratch with a fresh control.
To customize your control, right-click on it and select "Advanced »
Customize...". Please refer to the following tutorial for more
information on customizing controls:
LabVIEW Custom Controls, Indicators, and Type Definitions
Please let me know if you have any further questions, thanks.
