Flow Switch-FS-100ei

( Dwyer )

Feature:
The FS-100E version (with pre-adjusted set points 2.0. . .6.0 l/min) operates in vertical mounting position only. It is equipped with a calibrated piston which is displaced by liquid flow to magnetically actuate a hermetically sealed reed switch isolated within the unit body. When flow decreases the piston returns to its prior position by its own, weight and deactuates the reed switch. The FS-100E version (with pre-adjusted set points 5.0. . .15.0 l/min) operates with the same principle but a positive spring-return deactuates the switch when flow decreases. Mounting is possible in any position.
