This displacement is caused by the pressure differential from the air/water flowing through the unit. The magnetic piston actuates a hermetically sealed reed switch, which is encapsulated in the body of the unit, out of the air/water path. Decreasing the flow below the calibration point causes the reed switch to de-actuate.Actuation points for air at 68° F and 14.7 psia with increasing flowDeactuation (decreasing flow) averages 10% less than actuation (increasing flow)Flow setting accuracy ± 10% of calibration points shownRepeatability ±1%Unit will pass great flow State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
