Basically sometimes it'd be nice to know if the transfer pipe is full/empty/etc and do something based on that. It'd be ideal if you could make it so that you can hook it to a circuit connection to read the contents of the pipe. Bonus if it output not only the amount, but the max amount, and %full amount. these can both be done with decider/arithmetic, but at least being able to report the amount in the "tank/pump" would be great.
