I know that the turndown ration of the Orifice is about 3:1.
Suppose that the orifice is sized for 1000m3/h., then the rate that could sensed accurately would be 1000 to 3000, Am I correct?
Second the accuracy of a D/P cell is expressed in term of Calibrated span or Full range, then what is the minimum rate or Differential pressure that could be measured?
I would thank you for your help.
