| Operation |
When
flow is increased, the magnetic piston is forced against
a bias spring. As the magnet comes near the adjustable
read switch it actuates, indicating proper flow. When
flow decreases the spring forces the piston in the
opposite direction deactuating the reed switch and
indicating a reduced or no flow situation.
|
| |
| |
Actuation
points for air at 68 F and 14.7 PSIA with increasing
flow. |
| |
Deactuation
(decreasing flow) averages 40% 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. |
