Flush the instrument pressure lead to prevent the process medium from clogging it due to its viscosity or similar factors, and it also serves to prevent condensation
For example, media that are corrosive, have high viscosity, contain solids that can cause blockages, or are prone to condensation can all have an isolation fluid introduced to isolate the measuring elements and flush the associated pipelines
In addition to those listed above, antifreeze can also be used
