MC–Series: Gas Mass Flow Controllers

Full-scale flow rates between 0.5 SCCM and 5000 SLPM
Monitor four variables: mass flow, volumetric flow, pressure, and temperature
Control one of three variables: mass flow, volumetric flow, or pressure
98+ gas calibrations preloaded and user-selectable
Local, analog, or digital control, including industrial protocols

Beloved by metrology departments, cherished by researchers, and depended on by systems engineers – the MC-Series does more, and does it faster.

Steady state control range: 0.01% – 100% of full scale
NIST-traceable calibration
- Standard accuracy: ±0.6% of reading or ±0.1% of full scale, whichever is greater
- High accuracy: ±0.5% of reading or ±0.1% of full scale, whichever is greater
Repeatability: ±(0.1% of reading + 0.02% of full scale)
Typical control response time: as fast as 30 ms
Warm-up time: <1 s

Included with all MC-Series

Setpoint ramping and limits: Control your process as fast or slow as desired with ramp rates. Protect your process from inadvertent setpoint changes with setpoint limits.
Valve close and valve open override: Quickly stop all flow or vent your system as needed with alarms.
Totalizers and batch control: Track total flow every 1 ms or dispense precise volumes with our integrated totalizers.

Optimal performance for your unique process

Your controller may be built with one of the following valve options to maximize performance under expected process conditions.

MC: small proportional control valve for flow ranges of 20 SLPM and below
MC with PCA designation: high-performance proportional control valve used for some applications with higher pressures
MCP: small proportional control valve with the largest orifice (not available for corrosive configurations)
MCH: hammerhead configuration, which pairs two small valves working side-by-side as one valve
MCR: nearly frictionless large Rolamite proportional valve for flow rates of 50 SLPM and above

MCT: easily switch flow control between two different flow paths

Custom PID valve tuning offered for maximum performance in your process conditions.
