Georgeverghese,
Both instruments work for total level (level of liquid hydrocarbon).
They are installed in a position that is expected to have condensed hydrocarbon. So they are not designed to measure the interface between liquid HC and Glicol+water.
The tubing line that you mentioned is the...
Hello Danw2,
I used the following data to calculate the head temperature error:
See attached the error calculation from Rosemount Instrument Toolkit.

Danw2, thank you very much for your attention.
The graph unit is percentage.
The difference betwen the transmitters vary from 5% to 10% (most in 8% - 80mm in level as we have 1000mm between process connections).
In the graph, the yellow trend is the percentage difference betweem them.
As our...
Dear,
I am having problems with level measurement in a vessel.
In this vessel, we have 2 level transmitters (one for safety and one for control) and both are DP transmitter with diaphragm seal.
Those transmitters are connected in different process connection, being them:
- Control Level...
