BASIS Small Flow Meter for air and gas

Compact MEMS Thermal Mass Flow Meters

These small mass flow meters offer the performance of a premier product for processes with space constraints. These devices fit in the palm of your hand but are built to last.
• Accurate flow control in a compact, durable, metal flow body
• Run sophisticated flow-control scripts using a fast, robust Alicat ASCII command set
• Dispense doses and batches with built-in totalizer
• Switch between 9 gases: air, N2, O2, CH4, He, H2, Ar, CO2, N2O (via software BC-EVALKIT)
• 0.1-100% of full scale measurement and control range (1,000:1 turndown)
