Can you explain how you entered 9 feet on the range of mapping input and came out with a distance 5.9 = 78.13%? I'm guessing that calculation subtracts the blocking distance as well?
I have a question please. I have no other meaning of measuring the distance from the top to the water leve. No sounding pipe or sight glass. If i will measure in the stilling pipe with a measure tape the distance from the flange to the water level minus 50 cm I assume will be correct to introduce this value? Let's say that i have measured from the flange to the water a 3.5 m. Deduct 0.5 m from it,vwill result 3.0 m. So I will introduce 3 mtrs a mapping value. Thank you
