Description
New third-generation Quantim QMC Coriolis flow meters are ideal for very low-flow gas and liquid measurement and control applications.
Models QMC / QMB

Features:

  • True mass flow measurement
  • Accurate density measurement
  • NEW I/Os: 0-10 Vdc, 0-20 mA, RS485 S-Protocol
  • Variety of material options, enclosure types, and area classifications available
  • NEW easy-to-access external service port
  • NEW Quantim® QMC Coriolis series is form-, fit-, and function-compatible with prior Brooks Instrument Quantim® models

Benefits:

  • Process chemistry and conditions can be altered without changing or recalibrating the measurement system
  • All-stainless steel construction makes Quantim® QMC compatible with most process fluids
  • External service port, accessible via a 2.5 mm jack plug, coupled with Brooks Expert Support Tool (BEST) software, enables on-board alarms and diagnostics for enhanced process monitoring and predictive maintenance
  • Simplified installation, troubleshooting, and calibration verification

Applications:

  • Catalyst research
  • Mass balance calculations in chemical pilot plants
  • Liquid precursor delivery to vaporizers
  • Precision coatings
  • High-accuracy filling stations
  • Metering pump feedback/control loop
  • Vacuum processes
  • Semiconductor wafer processing
