On this page about Water integrator:
The Water Integrator was an early analog computer built in the Soviet Union in 1936. It functioned by careful manipulation of water through a room full of interconnected pipes and pumps. The level of water in various chambers (with precision to fractions of a millimeter) represented stored numbers, and the rate of flow between them represented mathematical operations. This machine was capable of solving non-homogeneous differential equations.
example, in the Water integrator the initial state was set by setting valve flow rates, and the amount of water in various containers of the machine.
