GE250A & GE300A mass flow controllers are general purpose, elastomer-sealed MFCs suited for a wide variety of applications.

The GE250A can be ranged from 100 to 250 slm (N₂ equivalent). The GE300A can be ranged from 150 to 300 slm (N₂ equivalent). Both are available with either analog I/O or digital I/O utilizing the latest control algorithms for fast and repeatable response to set point.

Settling times of 1 to 2 seconds and set point accuracies below 1% of setpoint exceeds typical high flow mass flow controllers. Precise control is maintained down to 2% of the configured Full Scale flow range. Multi-gas/multi-range capability and tight performance specifications for accuracy, control range, and transient response minimize flow controller inventory requirements.

The multi-gas/multi-range feature and other custom controls are accessed through the embedded diagnostic interface. A standard Ethernet cable and JAVA-enabled HTML browser are the only tools needed. Critical gas parameters for typical high flow rate gases are already stored on the MFC. Configure an G-Series mass flow controller by selecting the gas from a drop-down menu and specify the desired Full Scale flow range. Perform routine device health checks, plot flow response, and store operating data for offline analysis with the G-Series MFC diagnostic interface.

Key features

• Fast response to set point change reduces flow stabilization time
• Tight flow accuracy improves process matching
• Reduced inlet pressure (pressure drop) requirement simplifies gas supply regulation
• Multi-Gas/Multi-range reduced MFC inventory
• Configuration/diagnostics via Ethernet & web browser – no special software needed
