Best
As for me, I never saw technical drawing of fuel tanks used by manufacturers in free access.
Actually, we didn't need that - there is a trick you can use to check if there is any wall under drilling place: knock on the place of drilling and around it, if you hear thud - most probably there is a wall under, if sonorous - nothing under. Of course, you can use technological way as GoGPS proposed
Couple more words on calibration table: I would recommend as much calibration points as possible (as time allows you), not less than 10. Also, before doing calibration table, change "Signal filtration time" parameter to 0. Otherwise, you will loose 90 more seconds after each portion filling (as we did when were doing for the first time ). Do not forget to put it back in the end of installation procedure.
Also, we always store calibration table in sensor's memory - I do not recommend you to store it on the server side (yes, it has one advantage, but in general on-board processing of data is more preferable to ensure accuracy of measurement).
One more advice from my experience: after calibration is done - save the table to file and save the whole sensor's profile to file too. It would be very useful in case the sensor will break down and you will need to replace it with a new one.
