Quantim Series

Quantim® Series Coriolis Mass Flow Controllers & Meters

The industry standard for low-flow Coriolis measurement and control.

Models QMBC2 / QMBM2 / QMBC3 / QMBM3 / QMBC4 / QMBM4

Achieve superior accuracy and unmatched zero stability in ultra-low-flow gas and liquid measurement and control with the Quantim® Coriolis mass flow controllers and meters from Brooks Instrument. With the Quantim® series, Brooks has taken the lead in driving improvements in Coriolis flow technology: Our patented Quantim® Coriolis sensor design measures low flows independent of fluid type or process variables. The result: unsurpassed performance – the most accurate, stable, repeatable and reproducible mass flow measurement and control, even under changing conditions.

Features

True mass flow measurement
Accurate density measurement
100% of fluid flows through low-mass sensor tube (no bypass)
The Quantim® Coriolis series’ proprietary optical sensing technique enables accuracy at extreme low flows
Measures both liquids and gases over a wide flow range
Coplanar valve delivers super-fast response times
The Quantim® Coriolis series’ offers the smallest, lowest-flow Coriolis meter and controller available on the market
Measures and outputs two of four parameters: mass flow, volumetric flow, temperature, density
Independent diagnostic/service port and user display
Variety of material options, enclosure types and area classifications available

Benefits

Advanced sensor and tube technology enable accuracy at extreme low flows
Process chemistry and/or process conditions can be altered without the need to change or recalibrate the measurement system
Multivariable outputs improve and simplify process monitoring and diagnostics, increasing yields and reducing cost of ownership
Integrated sensor, valve and PID control in one package simplifies purchase, installation and startup
Reaches set point in <2 seconds reducing wasted material
Compact size enables easy integration into intricate process systems
The Quantim® Coriolis series’ has no internal moving parts, which minimizes maintenance

Key Applications
