M-50/55 Fixed Flow Switch
Brand: Malema
M-50/55 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.
Features- Very accurate custom flow settings
- For corrosive and non-corrosive liquids or gases
- All-Teflon® switch available
- Senses increasing or decreasing flow
- Hermetically sealed
- Universal mounting available
