Product Description

  • The FM10 features a 5/16” SS tube with 1” diameter SS floats. This durable design is ideal for corrosion-resistant applications where temperature and pressure may be a consideration.
  • The FM11 features a 5/16” SS tube with a 1” H x .75” Diameter PP float. This design is ideal for general use and potable water applications.
  • The FM12 features a 5/16” SS tube and 1” Diameter Buna float. This is ideal for petroleum products, hydraulic oils and wastewater.

These small, custom configured float switches are made for multi-point fluid detection in smaller tanks and are ideal for restrictive spaces. The FM10, FM11, and FM12 offer multiple custom fittings. Stainless steel 5/16” stems come standard with steel, Buna or plastic floats to offer corrosion resistance and versatility across a variety of liquid media. The multi-point liquid level sensors can be mounted externally through a 1” or larger NPT holes or mounted internally with smaller fittings.
