The NIVOFLOAT tilting level switch featuring mercury free contact is suitable for level switching of sewage, polluted liquids or drinking water. The double-chambered float and the sealing of the cable outlet provide hermetic sealing and water-proof operation. The float should be immersed to the required level and fixed if needed. At the given level, the float will switch by tilting. The special shape of the float ensures proper tilting without using a counterweight.
