Re-range of existing DP level installation


I am checking if the current span of one installed dp level transmitter is correct and giving correct reading. I cannot figure out the exact transmitter height with respect to the vessel. Is there any engineering document that gives me this info? It is a remote seal capillary installation for both LP and HP. In the data sheet it says the capillary length is 8 m. Should that be considered in the calculation equation? In the field, it is a wrapped capillary.

Thank u for help
