Quantim® QMC Coriolis Mass Flow Meters & Controllers

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

Models QMC / QMB

Achieve the most accurate, stable, repeatable and reproducible measurement and control of very low flow rates of liquid or gas with the new series of Quantim® QMC Coriolis flow meters and controllers from Brooks Instrument.

This third-generation Quantim® QMC Coriolis flow meter is engineered to improve process quality, production yield and throughput and reduce scale-up time from lab to pilot plant to production. The devices use a modern IoT-equipped digital architecture that, combined with the next-generation sensor design, enables faster response time with little to no overshoot when adjusting gas or fluid flow, improved zero stability and expanded I/O options.

In addition, Quantim® QMC Coriolis flow controllers provide multivariable outputs, including mass flow, volume flow, density and temperature. They also include a suite of advanced alarms and in situ diagnostics that actively monitor the process to identify system issues earlier and alert operators when mass flow controller maintenance or calibration is required.
