Gas Flow Controllers

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.
