| Operation
With no flow
present, the magnetic piston rests on the bottom of
the bypass bore. When flow is established the piston
is forced upward by the bypass flow and actuates the
reed switch. The bypass flow is controlled by manual
adjustment of the flow control vane. When flow decreases
the piston moves downward and the reed switch deactuates.
-
Actuation
points for air at 68*F and 14.7 PSIA with increasing
flow.
-
Deactuation
(decreasing flow) averages 10% less than actuation
(increasing flow).
-
Repeatability
± 2%.
-
Unit
will pass greater flows.
Corrections
must be made for other gases, line pressure and temperatures.
Please consult your representative or
