The comparison between the model compilation method of pneumatic ball valve and the model code of pneumatic ball valve shows that pneumatic ball valve is widely used and has a wide range of types. Understanding the meaning expressed by the number, specification and model of pneumatic ball valve is helpful to the selection, adoption and use of pneumatic ball valve.

(5) It can measure the flow of dirty medium, corrosive medium and suspended liquid-solid two-phase flow. This is because there are no moving parts inside the external measuring tube, and only the measuring tube lining and electrode touch the measured fluid. The data can be selected according to the nature of the measured fluid. For example, with polytetrafluoroethylene or polytetrafluoroethylene as the lining, various corrosive media such as acid, alkali and salt can be measured; Wear resistant rubber lining is especially suitable for measuring liquid-solid two-phase flow such as slurry and cement slurry with solid particles and greater wear, as well as suspended liquids such as various liquids with fibers and pulp.
