Description Specifications Literature Description Features: Close on-off differential Low maintenance Visual indication of flow with acrylic model No seals In line vertical plumbing Materials: Acrylic, brass, 316SS, or teflon Confirms: Normal flow condition Senses: High flow and low flow conditions Output: Switch contact Applications: Analyzers Kidney dialysis machines Micro biomedical Laser cooling systems Bubbler systems Pollution sampling equipment Operations:When air/water flows through the unit it causes the magnetic piston to move up at the calibration point. 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 flow Deactuation (decreasing flow) averages 10% less than actuation (increasing flow) Flow setting accuracy ± 10% of calibration points shown Repeatability ±1% Unit will pass great flow State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
