What is this device? I think it mixes fluids to precise ratios

I have some other pictures too, a little closer, but I couldn’t find much of any sort of labels or markings on it.

It was salvaged recently from an ITT, I’m not sure it was ever used.

I’d also like to find out approximately what it’s worth, since I’d ultimately like to sell it, once I figure out what it is.

Thanks.
