Float

The Series L10 Flotect® Mini-Size Float Switch is a series of economical, compact

liquid level oats. It is offered in brass or 303 SS bodies and external tees as well as polypropylene or 304 SS oats with 1˝ NPT male threads, for direct side mounting through a half coupling, or with factory installed tee for external mounting. This series can be used in liquids with specic gravities as low as 0.5.

FEATURES/BENEFITS

• Hermetically sealed, magnetically actuated SPST reed switch which is encapsulated in a polypropylene housing

• Simple eld switch adjustment allows user to toggle between normally open (NO) or normally closed (NC) with no change in the electrical connection

• Switch is easily replaced without affecting process installation for quick and low cost

maintenance

• Combines low cost with top quality materials and construction for great value and years of reliable liquid level control

APPLICATIONS

• Direct pump control for maintaining level

• Automatic tank dump operations

• Level control

• Valve control
