The KARI float switch is a control device for charging and discharging pumps and motor and magnetic valves. It is also an alarm device that alerts the user at specified surface levels. Thanks to its large float casing (Ø 170 mm), the KARI float switch has a buoyancy that guarantees smooth, trouble-free operation under all conditions. SGS FIMKO Oy (the Finnish Electrical Inspectorate) has performed testing in accordance with the Low Voltage Directive (LVD) and approved the KARI float switch for use in non-flammable liquids at 250 volts.
