MCV–Series: Vacuum Gas Mass Flow Controllers

Product description:

• Pneumatic shutoff valve. Equipped with a pneumatically actuated, positive shutoff valve to ensure no leak through.
• 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 gas mixtures.
• Easy integration. Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, PROFINET, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.

MCV-Series performance (most products)

• Available full scale ranges: 0.5 SCCM to 20 SLPM
• Steady state control range: 0.01% – 100% of full scale
• Standard accuracy calibration, NIST–traceable: ±0.6% of reading or ±0.1% of full scale, whichever is greater
• Optional high-accuracy calibration, NIST–traceable: ±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
• Pneumatic valve leak integrity: 1 x 10^-9 atm-cc/sec helium max
• Warm-up time: <1 s

MCE/MCV-Series operating conditions

• Compatible gases: 98+ preloaded selectable gas calibrations
• Operating temperature: –10°C to +60°C
• Full scale operating pressure: 160 PSIA
• Max differential pressure: 75 PSID
• Proof pressure: 175 PSIA
• User selectable reference conditions (defaults): 25°C & 1 ATM (STP) and 0°C & 1 ATM (NTP)

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.

Build and performance options

• Communication protocols: Analog, RS–232, RS–485, DeviceNet, EtherCAT, EtherNet/IP, Modbus RTU or TCP/IP, PROFIBUS, PROFINET
• Displays: Backlit monochrome or color; integrated or panel–mount
• Process connections: Compression, VCR, or VCO fittings
• Wetted materials: 302, 303, 304, 316L, and 430FR stainless steel; FKM, alumina ceramic, brass, glass, gold, heat-cured epoxy, heat-cured silicone rubber, polyamide, silicon
• Calibration: High-accuracy; custom calibration points

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.

• MCV: small proportional control valve mounted internally, plus an externally-mounted pneumatic shut-off valve located downstream

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