Model AS-FS Flow Sensor/Switch
Brand: Fluid Components International LLC (FCI)FCI’s AS-FS Dual Output flow sensor provides fully redundant and separate outputs in the same outline dimension envelope of single sensor output designs.
This is achieved by employing two electrically independent sensor heads and circuit boards; the second output assures continued operation in spite of a failure of one of the two redundant channels, thereby reducing the probability of an erroneous low flow or dry signal caused by a single sensor failure.
Features- No moving parts, no routine maintenance
- Small, compact and lightweight
- Simple installation Low flow sensitivity
- Wide turndown range; 100:1 or more
- Lowest pressure drop
- Extreme temperature, pressure and vibration service
- Highest reliability, 100,000 hours
- MTBF Corrosion, abrasion and fouling resistant
