Rosemount vortex flow meter
Thread Content
I’m using this to measure oxygen; what parameters need to be changed? Help, everyone.
Set the oxygen operating pressure, temperature, range, inner diameter of the pipeline, and flow K coefficient (indicated on the instrument’s nameplate); that’s all.
I would like to ask, what is the measurement accuracy?
I’m also struggling with the same problem. I tried to change the range manually, and it clearly indicated that the change was successful ； Yet, no changes are visible when checking on this transmitter.
If liquid oxygen is being measured, the applicable temperature is not quite right. If what is being measured is gaseous oxygen, why would the measurement medium indicated on the instrument be liquid?

Was it a flow meter taken from another place and used here? The medium is incorrect. . . .
You need to change the process variable from liquid to gas. Next, adjust the range units, process pressure, and temperature. For measuring steam, it is recommended to output the value in terms of volume, so that pressure compensation can be performed in the DCS system, which improves accuracy. If measurement isn’t necessary, then output the mass flow rate and set the density accordingly
