| Operation |
When
no flow is present the free magnetic piston is suspended
in the upper portion of the valve bore due to magnetic
repulsion between the lower fixed magnet and the piston.
As soon as flow is established the piston is displaced
downward and actuates the reed switch at the set point.
Set point is adjustable.

| |
| |
Actuation
Points for air at 68° F and 14.7 PSIA with
increasing flow |
| |
Deactuation
(decreasing flow) averages 30% 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 the factory. |
