Been working on some ideas, one being stacked gauges, the other is using two "sweeps" inside a gauge. The top gauge face shows what it would look like with each gauge at the max limit. Can't decide if I like this look or not. I'm still learning graphics design and this is a slow process for me. So, soliciting thoughts before I keep at this one.
Couldn't make the one above work for me, so I went a somewhat different direction
