| Operation
As flow is established
upward through the unit and continues to increase,
the pressure differential across the grooved magnetic
piston increases until it overcomes the small piston's
resistance (mass). The force causes it to progress
fully upward which actuates the dry reed switch. This
is a snap action and occurs in the decreasing mode
as well.
-
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 actuation points shown
-
Repeatability
± 1%
-
Unit
will pass greater flows.

Corrections
must be made for other gases, line pressure and temperatures.
