Flow can be controlled two ways, in most systems. Increase friction 
(turbulence) by a throttle valve, or reduce pressure with a constant, 
lower friction. The latter is hard to do, one tank at a time.

For slow flow rates, at high pressure, the size of the valve opening is 
very tiny. This means very good filtration is needed or the valve 
eventually clogs up.

One possible solution is a reservoir at tank height, filled via a float 
valve. The leads to the tanks could then be refrigerator ice-maker 
inverted "U" tubes filled with a yarn strand. Capillary action makes the 
tubes into self-starting siphons and the yarn distributes the friction so 
a particle or two don't clog the whole tube. Flow could be controlled by 
having two or more tubes to larger tanks. This is just one example of low 
pressure at low constant friction.
