The Alicat MCD Series Bidirectional Mass Flow Controller precisely and rapidly control the mass flow rate, volumetric flow rate and pressure of process gases in two flow directions via customized high-speed proportional control valves. The dual-valve design pairs a dedicated inlet valve with a dedicated exhaust valve, allowing a single MCD to control upstream and downstream flows, as well as positive pressure or backpressure in both open and closed systems.

The MCD Series produces volumetric and mass flow data that is fully compensated for changes in pressure and temperature and corrected for the user's STP. All mass flow instruments come with NIST-traceable calibration and generous customer support, including free technical phone support, prompt recalibration service and a lifetime warranty.

The MCD Series feature large integrated displays with user-accessible setpoint control and PID valve tuning without need for a computer. The MCD Series comes with 30 selectable gas calibrations and both analog and RS-232 digital communications. Extensive customizations are available, including Class 1, Div 2 CSA/ATEX ratings for use in hazardous environments. The series is also available with corrosion-resistant wetted materials (MCDS Series) or low pressure drop (MCDW Series).

The MCD Series are used in a variety of industries, from scientific research and gas analysis to leak testing and environmental monitoring. Dual valves, multi-variable measurement and control functionality, multiple gas calibrations and a 200:1 turndown ratio allow an MCD to be used as a universal control element, replacing several application-specific devices. Available 0.4% accuracy +0.2% full-scale repeatability and less than 100 ms control response times ensure top performance of gas flow processes.
