The HiTECH Intelligent NivoSwitch is a mechanical resonance system; excited, and kept in resonance by electronic circuitry. When the material level reaches the vibrating tines, it changes the vibration. This change is sensed by the electronic circuit; which activates the output. Unaffected by viscosity, foam, conductivity, dielectric, suspended solids, bubbles and/or turbulence, the NivoSwitch is ideal for a variety of liquid or free flowing granules or powder level applications, including: run dry protection, vessel overfill, and fill/dump control.
