The F124 ratio controller has been designed to ensure that two flows are kept at the same ratio even with changing flow rates. The controller ensures constant product quality and reduces the cost of blending. The F124 provides an alternative to pneumatic controllers in local control loops.
- Calculates and controls the ratio between flow A and flow B Formula: ratio = additive / main
- Three control modes:
- Hand (manual valve control)
- Local Setpoint (control additive flow only)
- Ratio (control additive flow to obtain the desired ratio).
- Displays actual and desired ratio simultaneously, flow rate A and flow rate B
- Safety mode to place the valve in a safe position
