I can draw a schematic if you are interested in. Better, you publish the actual volume-versus-angle curve of your concrete application here, then I can try to fit this curve by the above methode. I seriously need to recouch the thing in terms of actual pot angle. (please, not poti - to an english eye it looks like potty. ;-) and then I'll report in. I actually have had a request for a real product now. Calibration would be the real issue - this is liquid gas in the tank, and it utterly inaccessible except by calibration from an empty I think. And I think then I'd want to use a micro and a voltage controlled current source.... Also a simple diode limiter network could be used to fabricate the quasi cosine. But these diode limiters are prone to temperature drifts. I sincerely doubt that in this application the drifts would be THAT significant. Steve |
