FB21-040GK/A flow switch principle
Mechanical type flow switch. Spring support built-in baffle, when the flow rate reaches the value of prefabricated, mechanical structure trigger fretting trigger switch, online installation, small pressure loss, good reproducibility, anti pollution ability, precise switching is realized through the knob setting. Mechanical parts and electronic parts safety isolation.
