  • This male 8 has holes 8a connecting the inside of the sample cup and the outside to allow the fluid to flow out of the tip 14 as it is inserted into the tank.
  • Another intrinsic feature of the tool is its planned buoyancy. Due to its tubular shape 2, the volume of fluid displaced can be balanced with the weight force of each rod to create a safety feature that prevents the tool from falling into the tank, thus ensuring that it floats while being used.
