Miniature Float Switch

20300 series mini float switch
Designed for single point tank monitoring, compact liquid-level switches operate based on non-contact magnetic float and reed switch technology. This design allows for high accuracy fluid level detection of various liquids, including acids and chemicals. The compact style makes mini float switches perfect for tight spaces and small tanks, levels, and containers.

elobau’s miniature float type level switches are available in different materials for compatibility with a wide range of fluids, temperatures, and pressures. A robust design and durable housing give our float level switch a long operating life, even in demanding operating conditions.
Use our stainless steel and plastic mini float switches in a broad range of applications, including:
  • Potable water
  • Wastewater

Deciding Between Plastic or Stainless-Steel Float Type Level Switches

We designed our mini float switches for durability. To extend the life of your float type level switch and ensure accurate readings, however, you need to select the appropriate material for your operating environment and the fluid being measured.
Our PVC float type level switches are best suited for non-corrosive substances and standard operating temperatures. For high-temperature applications and those involving chemicals or other corrosives, polyamide, polypropylene, or stainless-steel level switches are your best option.  Stainless-steel also meets sterilization requirements for food, beverage, and medical applications.
