| Operation
When no flow is present the free
magnetic piston rests on the bottom of the bypass bore.
When flow is established the piston is forced upward
and actuates the reed switch. The bypass flow is controlled
by manual adjustment of the flow cotrol vane. When flow
decreases the piston moves downward and the reed switch
deactuates. The adjustment assemply is then locked down
to prevent any inadvertent readjustment.
-
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.
