F124 Ratio Controller
Brand: FluidwellThe F124 ratio controller has been designed to ensure that two flows are kept at the same ratio even if flows are changing.
The Fluidwell ratio controller will show a strong influence of maintaining a good and constant quality of products and saves money on the blending components.
The F124 is a key product of the Fluidwell Process Controller family and is the alternative to replace existing pneumatic controllers in local control loops.
Features- Controls the desired ratio between a main and an additive flow
- Displays flow rate A and B, alarms, ratio setpoint and actual ratio in percentage
- Safety mode input to place the controller in a safe predefined position
- Two alarm values can be entered in %: low and high ratio alarm
- Easy operation mode switching: Hand/Local/Ratio
- Explosion/flame proof Ex II 2 GD EEx d IIB T5
- Full Modbus communication RS232/485/TTL
- Loop or battery powered, 8 - 24 Vac / Vdc or 115 - 230 Vac power supply
