The wet leg should be installed with drainage that allows any liquid that accumulates or condenses to drain out. The drainage should be planned so that it doesn’t affect the DP transmitter’s precision.
Use Protective Sleeves:
The tubing can be covered with protective sleeves to shield it from physical harm and outside contamination. The fluid used in the wet leg should be compatible with the material used to make the sleeves, and they should be simple to clean.
Regular Cleaning and Maintenance:
It’s critical to do routine cleaning and maintenance on the wet leg to keep it clean and in good working order. The tube should be cleaned of any dirt or debris and checked for signs of damage or corrosion.
