I'm thinking of buying the 4 unit doser and I'm wondering if there is a way to calibrate the unit to dose accurately. I know you can set it to dose a certain amount in a day and that amount is based upon the duration of pump operation. But, I imagine that, depending on the length of tubing and head pressure, you will get a different amount of fluid pumped for a certain amount of time of pump operation.
