| 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.
-
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
