MC–Series: Gas Mass Flow Controllers
- Full-scale flow rates between 0.5 SCCM and 5000 SLPM for all gases (10,000 SLPM for H2)
- 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.

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.
Valve options
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
MCT: easily switch flow control between two different flow paths
Custom PID valve tuning offered for maximum performance in your process conditions.
