Digital Mass Flow Control alicat.com/mc Series Overview Alicat Scientific MC-Series digital mass flow controllers precisely measure and control the mass flow rate, volumetric flow rate and pressure of process gases via customized high-speed proportional control valves. They also measure and display gas temperature. At the heart of Alicat’s MC-Series mass flow controllers is a patented, internally compensated, laminar differential pressure measurement technology that yields linear results over a very wide flow range. This 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. With no internal moving parts or heating elements, the MC Series is electrically efficient and insensitive to bumps or changes in orientation. Alicat backs every mass flow instrument with generous customer support, including free technical phone support, prompt recalibration service and a lifetime warranty. Alicat MC-Series mass flow controllers feature large integrated displays with touchpad-accessible setpoint control and PID valve tuning. The MC Series comes with 30 selectable gas calibrations and analog and RS-232 digital communications. Extensive customizations are available, including Class 1, Div 2 ATEX/ CSA ratings for use in hazardous environments. The Series is available with corrosion-resistant wetted materials (MCS Series) and low pressure drop (MCW Series). Applications Alicat Scientific MC-Series digital mass flow controllers are used in a variety of industries, from scientific and analytical testing to manufacturing and metrology. Multi-variable measurement and control functionality, multiple gas calibrations and a low 200:1 turndown ratio allow a single MC-Series controller to replace several application-specific devices. Available 0.4% accuracy, 0.2% full-scale repeatability and <100 ms control response times ensure optimal performance of gas flow processes. The MC Series is available in full-scale mass flow rates from 0-0.5 sccm to 0-4000 slpm.
