Working principle Float level switches. When a liquid reaches the level where the level switch is positioned, its float follows the level variations in a such way that the articulated rod is moved. A magnet placed in the opposite side of this rod activates a switch. This switch can be either a micro-switch, a reed switch, an inductive detector or a pneumatic switch, depending on the application requirements.  Connections: EN 1092-1 DN65 flange Other sizes and flange standards on request Special square flange 92 x 92 / 108 x 108 mm  Mounting: side of the tank.
