Answer / sam

Ok I think I understand what you are asking. In most SMART
transmitters you have a digital indication on the
transmitter and you want to change what is displayed on this
indicator. You also said that you have changes the unit of
measure inside the transmitter with the HART, and this also
changed the UOM that is displayed.

There is a different parameter that you need to modify to
change the display. The parameter is normally something like
"set disply" or something like that.
Be aware that it will only display UOM or percentage or
display a switching between the two. What ever you have set
your UOM to inside the transmitter, will be displayed on the
indicator as the UOM. You cannot set the UOM to mmH2O inside
the transmitter and then display mBar on the display.
Also note that for a level application this display is
normally set to percentage and not UOM. If the operator look
at it he needs to see % level and not mm level. In a
pressure, flow or temp applications you want this display to
indicate UOM again.
Good luck

First of all,parameter's which need to be diagnostic in
transmitter with any of communicator will be in percentage .
Like for flow eg: Kgs,temp eg:cc fh level eg: % ,pressure
psi or bar.

Why flow/pressure transmitter before control valve?
