Materials of construction: All stainless steel/PTFE wetted components.
Rates: Zero to 5%
Methods: Continuous proportional control to main flowrate or fixed rate.
Control methods: Pulse width modulated or frequency modulated.
Features
- Intelligent additive injection systems from very low concentrations to 5% of main flow.
- Higher than 5% is usually blended continuously.
- High accuracy positive displacement flowmeters.
- High rangeability flow control valves.
- Protection strainers
- Compact design.
- Flush volume (no additive injected) at end of batch optional.
- Sample/calibration ports.
