A solution based on a MultiController E Regulate and a flow sensor calibrated for low air volocity is an energy efficient and secure way of maintaining air velocity in HEPA filtered cleanroom areas where a group of 0-10 Volt EC motors are used.
- Special flowsensor designed for use in cleanroom areas and laminar air flow units. Measuring range 0.1-1.0 m/s, 24V supply.
- The average downflow velocity should be 0.45 m/s ±0.05. All points measured must be within 20% of the calculated average. Downflow alam to be set 20% lower than the average downflow velocity though not lower than 0.32 m/s.
- Alarm relay for group motor failure and low flow.
