Our on-line analyzer is connected at the inlet of the pump, taken from the outlet pipeline of the shielded pump; after passing through the analyzer, the fluid returns to the inlet of this pump. But the outlet of this pump leads to the vacuum tower, where the pressure is around -91; could the negative pressure in that tower prevent the analyzer from accepting samples? Or siphoning may occur due to reasons such as a high flow rate at the pump outlet, preventing the analyzer from accessing the sample
The pressure sampling point is at the outlet of the shielded pump, with a pressure of -91. So how can the analyzer take samples? Why not take the pressure reading at the inlet instead, returning to the outlet of the shielded pump? What is the inlet pressure of the shielded pump?
