Also a new mem­ber of crow­tail fam­i­ly, it’s a Crow­tail- G1/2″ Water Flow Sen­sor. Water flow sen­sor con­sists of mag­net­ic core, rotat­ing impeller, exter­nal cas­ing and sen­sor and a hall-effect sen­sor. When water flows through the rotor, rotor rolls, it acti­vates the mag­net­ic core to trig­ger switch action speed changes with dif­fer­ent rate of flow. The hall-effect sen­sor out­puts the cor­re­spond­ing pulse sig­nals, users can get the flow speed via detect­ing the pulse. It is suit­able to detect flow in water dis­penser or cof­fee machine.     There are also lots of oth­er water flow sen­sors in oth­er diam­e­ters for your choice.     The water flow sen­sor out­puts pulse pro­por­tion­al to the water flow with: Pulse Fre­quen­cy = Flow *7.5. That is, if the out­put fre­quen­cy is 48, then the water flow: 48/7.5= 6.4(L/min) Con­nect the water flow sen­sor to micro­con­troller as belows:SpecificationMini. Wokring Volt­age: DC 4.5VMax.
