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.
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.
