| Operation |
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.
