Field accuracy reflects practical precision

 High measuring accuracy under ideal reference operating conditions is not everything. What is of crucial importance though, is that the devices do what they are supposed to do in everyday practical circumstances. Which is why calibration is accuracy’s best friend.



Take note

  • Accuracy is the one test no flow meter can afford to fail.
  • All flow meters require a periodic recalibration and verification.
  • Calibration and verification involve complex processes and jargon.
