MC Series Controllers
Mass Flow Controllers with Laminar Differential Pressure (DP) Technology
Our most versatile gas flow controllers for most industrial processes and research applications.
- Laminar DP (differential pressure) mass flow measurement technology
- 98-130 pre-loaded gas calibrations — switch without losing accuracy
- Measures mass flow, volumetric flow, temperature, and pressure
- Ultra–fast control response time as low as 30 ms
- As high as 0.01 – 100% measurement and control range (10,000:1 turndown)
- Limited Lifetime Warranty

- Accuracy as good as ± 0.4% of reading and ± 0.2% of full scale
- 1 – 100% of full scale control range
- As fast as 30 ms control response
MCQ Series Controller
Control gas flow at higher pressures
- 10 SCCM full scale – 12,000 SLPM full scale options
- 11.5 – 320 PSIA operating
- Accuracy as good as ± 0.6% of reading or ± 0.1% of full scale, whichever is greater
- 0.5% – 100% of full scale control (200:1 turndown)
- 100 ms control response
BIOC Series Controller
Control gases into bioreactors + fermenters
- Long‑term stability
- Robust, compliant materials including USP Class VI or USPVI elastomers
- Designed for scalability (10,000:1 operating range)
MCD Series Controller
Control flow in two directions
- 0.5 SCCM full scale – 3,000 SLPM full scale options
- 11.5 – 160 PSIA operating
- Accuracy as good as ± 0.5% of reading or ± 0.1% of full scale, whichever is greater
- Reference specs for MC, corrosion-resistant MCS, low pressure drop MCW, or high pressure MCQ. Performance is the same, but dimensions will change with addition of valve.
MCT Series Controller
Switch between two gas streams
TWO SOURCES, ONE DEVICE
- 98 gases
- 0.5 SCCM full scale – 3,000 SLPM full scale options
