 L312C Series Small Remote Chamber Level Switch   Printer Friendly Version
The L312 is a compact, single level switch contained in an all metal remote chamber and designed for installations where internal mounting inside the tank is impractical or impossible. The unit is mounted on the outside of the tank at the desired level of actuation and can be supported by the pipe connections. The switch and float mechanism is removable from the chamber without removing the entire unit from the tank. The aluminum housing comes with a brass mounting and a choice of Buna or stainless steel floats.
