M-60 Fixed Flow Switch

Brand: Malema

The M-60 flow switches monitor increasing and decreasing flow. 

They utilize a single moving part which responds to fluid (liquid or gas) flowing within a system. 

These switches are suitable for a wide range of applications used in semiconductor, industrial, biomedical, and OEM products. 

The flow monitors operate only when fluid flow is positively established. 

The M-60 is available standard with 1/4” Female NPT connections.
Features
  • For corrosive and non-corrosive liquids or gases
  • Very accurate custom flow settings
  • All-Teflon® switch available
  • Senses increasing or decreasing flow
  • Hermetically sealed
  • Universal mounting available
