The steam is passing through the tubes and heating the process fluid that is in the shell and I need the level of the steam/condensate in the head of the exchanger. The DP cells are being put on the head of the exchanger which is where the condensate will collect.
Hope this helps clarify. Thanks
All,
In order to understand the liquid level in a thermosyphon horizontal heat exchanger a differential pressure transmitter will be located on the head (top & bottom) of the exchanger to monitor liquid level. In this case, the steam is on the shell side and the process fluid is on the tubes...
