Thissensorsitsinlinewithyourwaterlineandcontainsapinwheelsensortomeasurehowmuchliquidhasmoved
throughit.There'sanintegratedmagnetichalleffectsensorthatoutputsanelectricalpulsewitheveryrevolution.
Thehalleffectsensorissealedfromthewaterpipeandallowsthesensortostaysafeanddry.
Thesensorcomeswiththreewires:red(524VDCpower),black(ground)andyellow(Halleffectpulseoutput).By
countingthepulsesfromtheoutputofthesensor,youcaneasilycalculatewaterflow.Eachpulseisapproximately
2.25milliliters.Notethisisn'taprecisionsensor,andthepulseratedoesvaryabitdependingontheflowrate,fluid
pressureandsensororientation.Itwillneedcarefulcalibrationifbetterthan10%precisionisrequired.However,its
greatforbasicmeasurementtasks!
