Description Specifications Literature Description Features: Non-Adjustable flow monitor Low maintenance Close on-off differential No seals Single moving part In line vertical plumbing Materials: 316SS, brass or PVC Confirms: Normal flow condition Senses: High flow or low flow conditions Water or explosion proof covers Output:Switch contact Applications: Laser cooling systems Heat pumps Cooling systems Operations: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 flow Flow setting accuracy ± 10% of actuation point Deactuation (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.
