Adjustable Automatic Bilge Pump Control
Pretty dang basic. Adjustable, small, works on fluid or gas, and does what it says. I keep the level at 0.01 just to avoid pumps glitching and staying on. You may want to use a flow valve to prevent back-feeding from kicking the pumps on and off every time the meter ticks by the set value.
Place a liquid meter in the compartment with the pickup ports.
Connect to the "Level" side of the meter.
Hook up the pump or pumps signal.
Enjoy watching water pour out of the crappy seaplane as it struggles to fly half full of water.
