Steam flow meters used for external settlement need to be calibrated; according to TSZJ125-2021, calibration can be carried out online, but can the accuracy obtained through online calibration replace that of offline calibration?

If you don’t understand, just ask. What do \"offline\" and \"online\" mean?

Online means performing verification while it is running, or stopping it without removing it for inspection; offline means removing it in order to conduct the inspection
