FLOW-SMS Surface Mount System
Brand: BronkhorstBronkhorst 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
