Siemens have expanded their range of water solutions by introducing the Wallace & Tiernan Single Function Controller (SFC), a single measurement unit that complements its current analyser and controller offering.
The Wallace & Tiernan SFC is useful in the measurement and control of disinfectants, allowing devices such as dosing pumps, electric stroke positioners and continuous actuators to maintain accurate and measured concentrations in one single unit.
The Wallace & Tiernan SFC is an addition to the currently used Multi-Function Controller (MFC), which can also maintain the same level of measurement performance as the single unit, but with the added ability of measuring more than one unit. Both units have modular designs and simple-to-operate functions.
The industries that benefit from the Wallace & Tiernan SFC instrument include:
- Industrial process water
- Swimming pools
- Public utilities
- Food and beverage
- Waste water plants
- Free chlorine
- Total chlorine
- pH value
- Redox voltage
- Chlorine dioxide
- Potassium permanganate
Both closed-loop and compound loop controls maintain a desired set point based on a measured value.
Due to its varied options, the Wallace & Tiernan SFC can cater to all conceivable water treatment applications, including single feedback closed-loop control.
The modular design of the Single Function Controller consists of:
- An electronic module
- A flow cell module
- A sensor measuring module
