NIVOFLOAT – Float Type Liquid Level Switch

Float Type Level Switch

The NIVOFLOAT NW-100 level float type liquid level switch is suitable for level changing of various liquids, especially wastewater in shafts, tanks, basins or cisterns. The double chamber float is made of injection molded rigid polypropylene (a type of tough and durable plastic) that provides good waterproof protection. The contacting microswitch is located in the float. With the experience of NIVELCO, the cable of the NIVOFLOAT NW-100 pear-type level switch is fed by the monolithic structure of the waterproof passage and injection molded plastic housing. The cable for the level float is a flexible insulated copper cable with a cross section of 3x 1 mm2 (AWG 17) and a PVC or Neoprene outer insulation. Different control tasks such as liquid level monitoring and pump control can be successfully performed with the NIVOFLOAT NLP-105-1.

Float Type Level Switch Operation
NIVOFLOAT float type level switch with mercury-free contact is suitable for level change of sewage, contaminated liquids or drinking water. The sealing of the double chamber float and cable outlet ensures hermetic sealing and waterproof operation. The float must be immersed to the desired level and, if necessary, fixed. At the specified level, the float will change by tilting. The special shape of the float ensures smooth tilting without the use of counterweights. Although it is mechanical among NIVELCO products, it is the most used product.
