M-55 Series Fixed Set Point Flow Switches from Malema
M-55 Series Fixed Set Point Flow Switches from Malema
The M-55 low flow, 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 in industrial, biomedical, and OEM products. The flow monitors operate only when fluid flow is positively established.
M-55 Series Fixed Set Point Flow Switches Features:
- For corrosive and non-corrosive gases or liquids
- Senses increasing or decreasing flow
- Very accurate custom flow settings
- Hermetically sealed
- All-PTFE switch available
- Universal mounting available
M-55 Series Fixed Set Point Flow Switches Applications:
- Pure water control for sample stations
- Laser equipment
- Pollution sampling equipment
