FB21-020GK/A flow switch principle

Mechanical flow switch. The built-in spring support plate, when the flow reaches the prefabricated value, the mechanical structure of micro trigger trigger switch, on-line installation, minimal pressure loss, good repeatability, anti pollution ability, set by the precise switch knob. The mechanical part and the electronic part ofthe security isolation.
