Need help with replacing sampled H2O.
I would like to use my 4th doser pump to replace saltwater used by the KDH.
How do I figure out the amount to replace?
The sample size is set to 65ml
The sample tube volume is 33ml
The measured waste is ~85ml
The sample pump draws 110ml and then returns unused portion
The reagent pump seems to use about ~1ml
By my calculations h2o taken from tank should be 110 - 33 = 77. However, based on waste quality it should be 85-1 = 84ml.
What am I missing?
Also, can the doser pull from ~50ft away?
