FINETEK Where should vane flow switch SF

FINETEK Where should vane type flow switch SF action principle in a closed metal or plastic pipe, set a point or points of the magnetic reed switch, and then the tube through one or more of the internal hollow ring magnet equipped float, and using a fixed ring, control float and reed switch in the relevant position, so that float fluctuate within a certain range. Use the float magnet to attract magnetic reed switch contacts, resulting in opening and closing action. Vane type flow switch is the use of water flow forces to bring leaves to test whether the liquid flow tube, when the liquid does not flow in the pipeline, spring down vanes perpendicular magnet, reed switch no action at this time, the contact in normally open (NO) position. When the liquid flow in the pipeline and the liquid flow is sufficient to push the blade height of about 20 ° ~ 30 °, the eccentric drive blades to push up the top of the magnet, the magnet of attraction of the magnetic reed switch action, this time turned contacts (close). Due to the different diameters of the blade length we have to change. ??
