John,
Excellent suggestion! Part of the reason I have been so reluctant to add new equipment is that we expect to find this problem in new installations where the tanks are practically unmodifyable. They will be double-bottom tanks below deck and adding level sensors will be a very painful process.
If I had the unit more easily accesible I would gladly try out some of the mechanical approaches. Adding new equipment aboard ship is much more difficult than it would be ashore.
Signal processing is also compounded by the combined effects of waves and ship course corrections - while steering through narrow Alaskan passages the tank's disturbance signal is certainly not sinusoidal!
I will post the results of trying this speed-master approach.
Thank you so much to everyone who posted, I had no idea that the response would be this enthusiastic!
Cheers,
-Antony
