FLOW-SMS Surface Mount System

Brand: Bronkhorst

Bronkhorst developed the FLOW-SMS series for customers who are looking for process gas panels with optimal space efficiency.

On a compact, lightweight but still rugged mounting rail system one or more mass flow or pressure sensor modules can be combined with control valves, shut-off valves, mixing chambers, filters or any other functional module as per customer’s request.

The modular concept of the FLOW-SMS system offers great flexibility for the end-user with respect to modifications and serviceability.

The functional modules are ‘top-mount’, so they can easily be exchanged without removing the total assembly.
Features
  • Compact assembly ensures space efficiency and minimized dead volume 
  • Economical solution, low cost of ownership
  • Tubeless construction reduces potential leak points
  • Service friendly, easily accessible from the top
  • Great flexibility regarding system extension or modification
  • Pre-tested “Plug and Work” units, reducing custom testing requirements
  • Analog or digital communication (RS232, DeviceNet, PROFIBUS DP, Modbus, EtherCAT, PROFINET, FLOW-BUS)
  • Optional PROFIBUS Gateway offering cost-effectiveness at 3 or more channels
  • Alarm and counter functions
  • Control characteristics user-configurable
  • Optional multi gas / multi range functionality
  • Free software tools
