Kelly Pneumatics, Inc. offers a reduced cost, single or dual-valve design, Mass Flow Controller for low volume flow applications. The unit is calibrated for up to +-0.5% accuracy (full scale) for flow rates of 0-10 lpm. For greater accuracy, the unit can be customized to +-2% of reading. This mass flow controller can also adjust for back pressures of up to 100 psig, as well as compensate for changes in gas temperature. The controller can also be customized for response times of up to 20 milliseconds (full scale). This unit can accurately control numerous gases, including Air, Oxygen, Nitrogen, Argon, and many more.

Further customization is possible due to an internal microcontroller. Change your response time, control range, or incorporate additional control or feedback signals, with customized software, modified to meet your most demanding flow control applications.
