Description
The FS-100E version (with pre-adjustable set points 2.0. . .6.0l/min) operates in vertical mounting position only. It is equipment 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-adjustable set points 5.0. . . 15.0 l/min) operates with the same principle but a positive spring-return deactuates the switch when flow decreases. The FS-100E-A (adjustment range 1.0 . . . 16.0 l/min) operates according to the same principle as the FS-100E with spring. The FS-100E-A is provided with an additional scale on the brass body on which set points as well as setting functions can be adjusted in one operation. Only the mark of the junction box has to be moved over the respective scale value. Pressure drop is not influenced at all when changing set points.
