Gas Flow Ratio Control [GFRC]

The Gas Flow Ratio Control gassing strategy utilizes two flow paths, each with mass flow controllers, one for Air and one for O2 flow. Flow meters visually indicate the flow of Air and O2.  Both mass flow controllers can be operated manually or automatically in conjunction with the DO controller. The DO controller can be user adjusted to keep e.g. the total flow or the ratio of the Air and O2 constant.

• Two (2) integrated Mass Flow Controllers for Air and Oxygen controlled via DO control loop
• Integrated Rotameter with manual control valve for gas flow control
• Also applicable to sheer stress sensitive cells and filamentous organisms
