PFGLP22 float level indicator for liquids

Float level switch. Takes advantage of the buoyancy principle. Movement of the float is transmitted to a magnet which switches a signal micro switch. The float and casing are separated by a hermetic stainless steel barrier. Does not require a power supply to operate.



  • Ideal for use in contact with corrosive materials or food products.
  • Easy to install: specific tools or settings are not required.
  • Enhanced protection level in the presence of explosive dusts/powders and gas.
