Alicat Scientific MCR | High-Flow Mass Flow Controller | 250-12,000 SLPM, rolamite valve
The Alicat Scientific MCR is the high-flow version of the MC controller, using a rolamite valve for full scales of 250 to 12,000 SLPM in the MC 50-12,000 SLPM spec sheet. Standard accuracy is ±0.8% of reading and ±0.2% of full scale, with a 500:1 control range and response as fast as 100 ms. Pressure drop at full scale runs from 2.4 PSID at 250 SLPM to 72 PSID at 12,000 SLPM.
Key features
- Rolamite valve, mounted upright
- Default female NPT ports from 1/2 in to 2 in depending on range
- Repeatability ±0.2% of reading and ±0.02% of full scale
- Operating temperature -10 to 60 °C
- 24 Vdc supply, current rising with range
