Mass or Volume Flow Controller
Mass Flow Controller and Volumetric Flow Controller Features Measured Parameters MC & MCR Series Mass Flow Controller products • Mass Flow • Volumetric Flow • Pressure (PSIA) • Temperature (° Celsius or ° Farenheit)

VC & VCR Series Volumetric Flow Meter products • Volumetric Flow

Versatility • Pressure and temperature measurements are taken and displayed in the same unit alleviating the need for additional measurement devices. (MC & MCR Series) • Mass flow controllers can be set by user to control pressure. It’s like having 2 instruments in one. (MC & MCR Series) • MFCs can be tuned for application specific control • Multiple digital & analog inputs and outputs • 100:1 Turndown ratio • 30-Gas Select on all units to reduce inventory costs • Control range from 1% to 100% of full scale flow • Tunable P & D to fine tune instrument’s speed of response • Optional Remote Display allows for panel mount of the display with full pushbutton control in embedded applications • Optional Remote Electronics allows devices to be installed in high heat applications by separating the flow element from the electronics.

30 factory installed, user selectable, gas calibrations: • Air • Argon • Methane • Carbon Monoxide • Carbon Dioxide • Ethane • Hydrogen • Helium • Nitrogen • Nitrous Oxide • Neon • Oxygen • Propane • Butane • Acetylene • Ethylene • Iso-Butane • Krypton • Xenon • Sulfur Hexaflouride • 75% Argon + 25% C02 • 90% Argon + 10% C02 • 92% Argon + 8% C02 • 98% Argon + 2% C02 • 75% Argon + 25% Helium • 75% Helium + 25% Argon • 75% CO2 + 25% Argon • Helistar® A1025 • Stargon® CS • 95% Argon + 5% CH4
