Description Specifications Literature Description Features:Adjustable flow monitorMonitors both gases and liquidsMaterials: Brass or 316SSConfirms: Normal flow conditionsSenses: High flow or low flow conditionsOutput: Switch contactApplications:Process mediaFire control systemsCooling systemsHeat pumpsHydraulic liftsWater treatment chemicalsOperations:When flow is increased, the magnetic piston is forced against a bias spring. As the magnet comes near the adjustable reed switch it actuates, indicating proper flow. When flow decreases the spring forces the piston in the opposite direction deactuating the reed switch and indicating a reduce or now flow condition.Actuation points for air at 68°F and 14.7 psia with increasing flowDeactuation (decreasing flow) averages 40% less than actuation (increasing flow)Repeatability ±2%Unit will pass greater flows State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
