M-62 Fixed Flow Switch

Brand: Malema

The M-62 inline flow switches monitor increasing or decreasing flow. 

The M-62 flow switch’s construction comprises of an all-PFA molded body with a PTFE encapsulated magnetic piston. 

The all PFA and PTFE design makes the M-62 flow switch compatible for caustic fluids. 

The magnetized piston actuates a hermetically sealed reed switch in response to fluid flows. 

The M-62 switch is suitable for a wide range of applications in industrial, biomedical and semiconductor industries, especially where highly corrosive fluids are used.
Features
  • For corrosive and non-corrosive liquids or gases
  • Senses increasing or decreasing flow
  • Custom flow settings
  • Ideally suited for high purity application
  • Low maintanance
