DATA SHEET Mass Flow Controllers & Meters Low Flow Coriolis Mass Flow Controllers & Meters for Liquids & Gases Brooks Instrument has developed the third generation of its small, low-flow Coriolis mass flow meter and controller – the new Quantim® QMC Series. Compatible in fit, form and function with second generation QMB models, the new QMC model features a modern digital architecture enabling fast response, expanded simultaneous multi-variable outputs and enhanced diagnostics to handle a wide range of challenging applications. A new easyto-access service port and status LEDs on the top lid simplifies installation, setup and troubleshooting using our free BEST (Brooks Expert Support Tool) software. The heart of the device is a unique high-performance Coriolis sensor which directly measures mass flow independent of fluid type and process variables. With a range of 0.001 to more than 27 kg/hr, this multi-variable device simultaneously measures and reports mass flow, volume flow, density and temperature along with other valuable diagnostic variables for optimized process control and predictive maintenance. Quantim® offers unsurpassed accuracy and zero stability in for demanding low flow applications. Most critical processes require control as well as measurement, and Quantim® offers an integrally mounted, in-line control valve. The integrated control valve and on-board control electronics simplify the installation, setup, operation and maintenance versus other low flow measurement and control techniques. No remote electronics are required as all the transmitting and control electronics are contained within the product housing.

Precision for Critical Low Flow Processes Coriolis technology enables precise, direct mass measurement and control for very low flow processes. This technology enables measurement accuracies within 0.2% of rate for liquid applications and 0.5% of rate for gas applications. The configuration with the lowest flow capability allows for measurement and control down to 0.001 kg/hr, which is perfect for chemical and petrochemical research, semiconductor, industrial thin film and other critical low flow processes. Process Flexibility The Coriolis flow measurement technique eliminates the need for...

Notes 1 The nominal flow rate is the flow rate at which water at reference conditions causes approximately 1 bar of pressure drop or the laminar to turbulent transition flow whichever is lower. Maximum flow rate is higher than the nominal flow rate and is dependent upon process fluid and process conditions. 2 Standard volumetric conditions are 14.696 psia and 70°F. 3 Actual volumetric flow is a function of the mass flow and the density measurements; therefore the accuracy of actual volumetric flow is a function of the mass flow and density accuracy. 4 Accuracy includes combined...
