What is this dial on the organ in the Berliner Dom?

Question

What is this dial on the organ in the Berliner Dom?

I am guessing that the dial may have something to do with air pressure but why would it be needed and what units do the numbers represent?

Here is the performance where the dial is first shown - Warning Loud!"

Could be a crescendo indicator dial. It is used to know what is the current position of the crescendo pedal on some organ.

Thanks - that sounds highly likely although I haven't yet been able to confirm online that this particular organ has a crescendo pedal.

The Sauer organ in the Berliner Dom has a crescendo pedal. That's the "Registercrescendo" in the "Spielhilfen" listed on the German language page. The Sauer organ has 113 registers. The dial is marked to 104, so I would assume that only 104 of the total registers are connected to the crescendo pedal. The display shows how many of the available registers are selected.
