If the silo is supported on load cells, the bottom of the silo would need to be built heavier to withstand the point loading, as opposed to the setting the silo on the ground. I doubt if it would be practical.

Another thing to keep in mind, is the cone points up when it is loaded, and down when its emptied. On large silos there may be multiple loading and undloading points, creating multiple cones that aren't centered. We grind 120,000 bu of corn a day at the plant. We don't use level transmitters on the corn silos. While there are some transmitter out there that will work, its easier to keep track of how much was put in and taken out than to try to rely on a level transmitter. We have high level probes so we don't overfill on accident. For monthly inventories we use the old fashion plumb bob on a
tape.
