MCVS–Series: Anti-Corrosive Vacuum Gas Mass Flow Controllers
Use MCVS-Series Anti-Corrosive Vacuum Gas Mass Flow Controllers are equipped with a pneumatic shutoff valve, and can be used to control mass flow or pressure of 128+ gases (including 30+ corrosives) in vacuum applications.
- Pneumatic shutoff valve. Equipped with a pneumatically actuated, positive shutoff valve to ensure no leak through.
- Aggressive gas compatibility. Wetted materials compatible with 30+ pure corrosive gases and most refrigerant gases.
- Versatile & accurate. Real-time control with NIST-traceable accuracy to ±0.5% of reading or ±0.1% of full scale for 128+ gases and 20 custom-defined gas mixtures.
- 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 130+ 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.
