Description Specifications Literature Description Features:Non-Adjustable flow monitorLow maintenanceClose on-off differentialNo sealsSingle moving partIn line vertical plumbingMaterials: 316SS, brass or PVCConfirms: Normal flow conditionSenses: High flow or low flow conditionsWater or explosion proof coversOutput:Switch contactApplications:Laser cooling systemsHeat pumpsCooling systemsOperations:As flow is established upward through the unit and continues to increase, the pressure differential across the magnetic piston increases until it overcomes the magnetic piston's resistance (mass). This force causes it to progress fully upward to actuate the dry reed switch. This is a snap action and occurs in the decreasing mode as well.Actuation points for increasing flowFlow setting accuracy ± 10% of actuation pointDeactuation (decreasing flow) averages 10% 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.
