That must be horrible! Hah. There have been discussions on sensing keg volume in a few different threads, but I'll more than likely go with weight sensors under each keg. The downside is that the majority of weight sensors are meant for instantaneous readings and drift when under a constant load. There are some things I can do to mitigate the issues, but the only other worthwhile solution would be flow sensors. Cheap ones aren't terribly accurate and accurate ones are terribly expensive.
