SUM THREE UNEQUAL FLOWS
Flow #1: Full Scale (20mA) = 1.75 MGD (Million Gallons per Day)
Flow #2: Full Scale (20mA) = 22 MGD
Flow #3: Full Scale (20mA) = 1.04 MGD
Module Output: Full Scale (20mA) = 24.79 MGD
Something we do all the time - modify our products to meet out-of-the-ordinary needs. In this case the customer needed to add signals from three flowmeters, each having a different scale factor.
A bit of engineering calculation, followed by the selection of a few precisely-measured input resistors, did the trick.
