We never used dye. The operator has a stainless sink that drains into the
slop tank. In it is a large graduated cylinder. The faucet samples the
incoming line and pours into the cylinder; it oveflows into the sink. He
has an approprite hydrometer bobbing in it.

Over 20 years ago I had the chance to tour the pumping and fuel
distribution control facility at a refinery. *Everything* was
controlled from that room. They measured flow rates
Vs time and claimed they could control the flow to the remote storage
facilities hundreds of miles away within several gallons. the system
was automated. The operator told it how many gallons of what to go
where. Different mixes and fuels were sent through the same pipeline
with no one on the other end to either make the switch or to monitor
it.


Were it only that the ATC system was so automatic, instead of so antiquated.
