That reminds me of the hydraulic MONIAC computer [0]. ("Monetary National Income Analogue Computer")

Or perhaps the ancient greek"hydraulic telegraph" [0], which (sadly) was not a pipe-based communication system, but two independent pre-calibrated water-clocks. The signals were sent by flaming torch, but by measuring the duration of the light more information could be sent.

Great video and animations, along with very interesting food for thought in the possible arguments for this solution over a proportional solution.
