C-Series Overview

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.

A low thermal mass MEMS sensor provides rapid sensing of flow changes with low noise output. The solid state design of the sensor makes it resistant to water condensation, particles, pressure shock and vibration.

Fast response, wide dynamic control range, and 0.8% of set point accuracy make this MFC an excellent choice for flow control in critical process applications where noncorrosive gases are used. Typical uses can be found in mass spectroscopy, vacuum coating, bioreactor as well as many other applications. 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.
