MC–Series: Gas Mass Flow Controllers

MC-Series Gas Mass Flow Controllers rapidly reach setpoints and maintain stable control of mass flow, volumetric flow, or pressure for 98+ gases across a very wide flow range – 0.01% to 100% of full scale.
  • Versatile & accurate. Real-time control with NIST-traceable accuracy to ±0.5% of reading or ±0.1% of full scale for 98+ gases and 20 custom-defined mixtures.
  • Fast control, multivariate data. Millisecond-response times immediately upon powering up, to control either mass flow, volumetric flow, or pressure and display instantaneous flow, pressure, and temperature readings, in your choice of engineering units.
  • Easy integration. Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.

Device Features
Included with each device
  • Multi-variable process measurements: Simultaneously measure mass flow, volumetric flow, gas pressure, and gas temperature.
  • User changeable units of measurement: Change the unit of measurement for pressure, flow, or temperature from our extensive list of engineering units.
  • Gas selectability: Select your process gas from any of the 98+ preloaded NIST-traceable gas calibrations in our gas list.
  • Gas Select COMPOSER™: Define 20 custom gas mixtures of up to 5 constituent gases using our Gas Select Composer firmware.
  • Monochrome backlit LCD with integrated touchpad: Easily read measurements using the backlit display and control configurations with the user-friendly integrated touchpad.
  • User adjustable setpoint ramping & limits: Configurable ramp rates allow the process variable to be controlled as fast or as slow as desired, and configurable setpoint limits protect processes from inadvertent setpoint changes.
  • User adjustable standard temperature and pressure (STP) conditions: Quickly change reference conditions without need for recalibration.
  • Valve close override and valve open override: Utilize alarms to quickly vent your system or stop all flow as needed.

Valve options & PID tuning

Your mass flow controller may be customized with one of the following valving options to ensure optimal performance under your 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

Custom PID valve tuning ensures maximum performance for your specific process conditions.
