Based on the theory of two-phase flow, the mechanism of the condenser's steam resistance which is influenced by the steam velocity field at the condenser's throat outlet was analyzed.

The major factors for the erosion corrosion of the steam ejection pump in the decarbonization system were media temperature, electrolyte and depolarization of oxygen in addition to flow velocity.

It can be used to measure liquid, gas, and steam flow, especially suitable for small low-velocity flow measurement medium flow.
