I'm looking for a way to vaporize 20 lbs/hour of liquid CO2 from a
refrigerated bulk tank and deliver the gas at about 100 psi.

Does anyone know of a ready supplier of such a device?

I've talked to the industrial suppliers, and their smallest units are
100 kgs/hour for chemical and brewing plants. Seems like they use similar
devices for LN2 vaporization in semiconductor processing, maybe at a
smaller scale?

I've considered improvising something with a tubing coil immersed in a
heated water bath, but it isn't clear how you can meter the liquid input
for an intermittent draw on the gas out.

This is for a small carbonation/bottling plant, running 1200 liters/hour
of
beverage.

Why do you need to meter the liquid input? Doesn't the 100 psi output meter
the input automatically?

I'd use a coiled line like you suggested, and regulate the output with a
paintball regulator.
