No.
You would have to have them adjusted equally. The Uni-syn is a meter, measuring the amount of air the engine is sucking thru it.
What is happening is that "thingy" I was talking about in the middle is adjustable opening that the air flows past. It screws up and down, thus varying the amount of air flow going past the opening that creates vacuum to make the ball  float.
This is how you can balance both carbs to the same flow. Whatever the first carb is, you adjust the second to match the first. You move the Uni-syn over to the second without changing the Uni-syn adjustment.
This often entails back and forth adjustments from one to the other. If the first carb is flowing more or less air, you cannot adjust the second to match. So you might have to adjust the first then go to the second, several times, until you have them equal, balanced.
Gotta go, hope this helped.

If you had two of these could you put one on each carb and then adjust them accordingly ?

Mine is for 2 bbl carbs. I made an adapter for 4bbl. carbs, still works
same way.
Looked on ebay and there are many, near 80 listed.
Most the same, I have model A, not sure what the ones with the pipes are
for, maybe for measuring vacuum ports.
I didn't mention, works on side draft carbs as well.

Looking at the photos, what happens is you set it on top of the carb with
engine running. adjust the thingy in the middle more open or closed until
the red ball is floating in the calibrated tube.
Then take off the carb and put on the other and see where the ball floats.
That tells you how much or less air is flowing into the engine.
Idea being, you adjust carbs until the ball floats in the same place on
each carb.
Once done, both are flowing the same and running smooth, hopefully.

I used it originally on Volvo Penta Marine engines. They usually had 3
deuces, and i did it while they were sitting dockside. Then a run down the
river to the Chesapeake Bay.
Once right, engine screaming, up on plane, and a beer in hand... Such fun.
Later, hundreds of Dual carb VW engines, when I had my business.
Also, tuning my 348 tri-power and my 409/425hp Chebbies. Crap, wish I had
them today...
Worse part is, that was all in the first 1/2 of my life. I thought it would
take much longer to get old!
