Brooks Instrument Quantim QMC Coriolis mass flow controllers

Brooks Instrument has released the Quantim QMC Coriolis mass flow controllers (MFCs), designed to provide high accuracy for very low flows of liquids and gases.

Suitable for applications such as catalyst research, mass balance calculations in chemical pilot plants, thin film coating and surface treatments, fibre-optic cable production and semiconductor wafer processing, Coriolis flow meters and controllers use direct mass flow technology for more accurate flow measurement.

The Quantim QMC Coriolis MFCs feature a stainless steel sensor that measures low flows independent of fluid type or process variables. Accuracy is specified at 0.2% of rate for liquids and 0.5% for gases. It also supports improved zero stability, which is said to provide more precise accuracy at the low end of its operating range.

This third-generation Quantim QMC Coriolis series 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 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.

In addition, the MFCs provide multivariable outputs, including mass flow, volume flow, density and temperature. They also include a suite of alarms and in-situ diagnostics that actively monitor the process. This functionality can be used to identify system issues earlier and alert operators when MFC maintenance or calibration is required.
