On a cylindrical LPG tank, where are the dip pipes located?

Dip pipes are typically located within 6 inches of the midpoint of a cylindrical LPG tank. This positioning is critical for ensuring accurate measurement of the liquid level in the tank. Placing the dip pipe near the midpoint allows for a representative sample of the liquid in the tank, as it reduces the influence of potential sedimentation or other materials that may settle at the bottom. Additionally, this placement helps in achieving a more consistent measurement by balancing the effects of temperature variations and liquid movement that might occur within the tank.

In contrast, dip pipes positioned at the bottom of the tank could be affected by sediment or other non-liquid materials that may accumulate there, leading to inaccurate readings. Similarly, dip pipes located at the top of the tank would not provide a measure of the liquid level at all, as they would be measuring gas rather than liquid. Therefore, situating the dip pipes within 6 inches of the midpoint is the standard practice for effective measurement in LPG tanks.
