What causes the remote display of the orifice flow meter on the steam pipeline to show NAN?
In my opinion, what you should ask about is remote display; remote transmission is a concept related to pressure transmitters. When remote display shows NAN on a DCS system, it indicates that there is an error in the data. There are many possible reasons for this, such as measurement issues – for example, the flow rate might be too low to be measured accurately； There was a problem with the installation; the signal wasn’t connected properly, so it couldn’t access the control system and no display appeared ； There’s a problem with the configuration; the measured data cannot be displayed, and so on
