Re: litermeter 3
(1) Calibrate all the pumps per the instructions in the manual.
(2) Set up one pump to drain x gallons of SW per day, with a float switch to turn it off if the water drops below a certain level.
(3) Set up another pump to add the same x gallons of SW per day, with a float switch to turn it off if the water exceeds a certain level.
(4) Set up the third pump to top off with RO/DI for the amount of evaporation loss per day, with a float switch to turn it off if the water exceeds a certain level.
