    OPERATIONWhen 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 greater flows.

  • OPERATIONAs flow is established upward through the unit and contin-ues to increase, the pressure differential across the magnet-ic piston increases until it overcomes the magnetic pistons 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.
