The C-Series compact design is only 1 inch (25.4 mm) and less than 4.4 inches (111.8 mm) high. It has standard lengths of 4.88 inches (124 mm) for 4 VCR® male and 4.54 inches (113 mm) for 0.25 inch compression seal gas line connections. Downmount versions are also available.

The C-Series incorporates a fast-acting solenoid control valve coupled with the flow sensor via the MFC’s superior flow signal processing and control algorithm. This results in response times to set point of less than 100 milliseconds.
