Overview
Fast mass flow controllers and meters make process control and calibration processes more efficient. Alicat offers many ways to customize your gas flow meter or controller for use in low pressure drop, high pressure or corrosive applications. Standard features include real-time readings, fast valve response and multi-gas calibration. Most models can be customized for flow rates as high as 5000 slpm or as low as 2.5 sµlm/0.0025 sccm.

Gas mass flow controllers must be fast and accurate to establish stable flow. Our mass flow controllers reach their setpoints faster than any others, which enables them to suppress fluctuations in line pressure before they affect your process downstream. Customized valve options and factory PID tuning ensure that your MFC will perform well in your specific application.
The MC series is our standard mass flow controller, with models that can measure flow rates as high as 5000 slpm or as low as 0.0025 sccm. Choose an MCQ when your line pressures are high (145-305 psig). The MCW series is best for low pressure drop applications, leak testing and for reducing pneumatic response time at flow rates of 50 scccm or less.
If you need a drop-in replacement for an existing thermal mass flow controller, the MCE series tucks the valve inside to conform its process connections to the SEMI standard length. For vacuum applications, the MCV adds a pneumatically-actuated shut-off valve to the MCE form factor.
BASIS is Alicat’s line of compact mass flow controllers designed for OEM applications and large-quantity orders.

Multi-directional gas flow controllers
Open in new windowSometimes a process is too complex for a standard mass flow controller. Alicat’s multi-directional mass flow controllers consolidate into one instrument what would otherwise require two or three separate devices.
When you need to control flow in two directions, choose the world’s first bidirectional mass flow controller, Alicat’s MCD series. This versatile instrument can control flow into a closed volume and then control flow in the other direction to exhaust the volume. Or, you can use vacuum to control your process flow in one direction and then apply positive pressure to purge the line in the other direction. The MCDW applies our Whisper technology with low pressure drop to bidirectional applications like breathing simulations.
Choose the MCT series if you want to control flow in only one direction, but you need to switch the sources of flow or its destinations downstream. Dual valves located upstream, downstream or in both locations help you manage your flowing processes more efficiently.
Liquid flow controllers and meters
Open in new windowAlicat’s liquid flow controllers and meters offer accurate flow measurement and stable control for water or other liquids, including methanol, iso-propanol, ethanol, ammonia, dimethylether, iso-pentane, thiophene, iso-octane or heptane. All liquid flow instruments include bleed screws for easy removal of air pockets.
The LC series of liquid flow controllers features fast-acting proportional valves for control or dispensing applications.
For liquid flow measurement without a control valve, choose our L series of fast liquid flow meters, which measure flow, pressure and temperature in real time. Our LB series adds a rechargeable battery for easy audits of liquid flows outside of your lab.

MCD–Bidirectional Gas Mass Flow Controllers
The most versatile gas flow controller in the world
Alicat’s MCD is the world’s first bidirectional mass flow controller. Control flows into your flowing or closed process in one direction, and then reverse flow with multivariate measurement of flow, pressure and temperature in each direction. Or control flow into a closed process using pressure control while monitoring flow rates, and then vent the volume with no need for additional bleed valves. We’ll use your application parameters to customize your valve and PID tuning to ensure that it delivers fast and stable control, in both directions.
- Versatile. Control flow with positive pressure or vacuum in one or both directions. Or control pressure into flowing or dead-ended processes. (Download our infographic on the right for flow diagrams.) In all cases, flow measurement is multivariate (mass flow, volumetric flow, pressure and temperature), and you can select another gas calibration on the fly or define your own gas composition with COMPOSER™.
- Connected. Easy integration into your digital industrial network with Ethernet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP) or serial communications options.
- Durable. MCD series flow controllers can temporarily flow liquids without getting destroyed. For environmental hardiness, we can build your flow controller with IP66 ingress protection.
Alicat’s MCD series uses small proportional valves for control at lower flow rates and is suitable for use with non-corrosive gases.

MCDW–Low Pressure Drop Bidirectional Gas Mass Flow Controllers
The most versatile gas flow controller, with minimal system impact
“Whisper” series bidirectional mass flow controllers with low pressure drop are ideal for controlling mass and volumetric flow rates when there is little available system pressure. Low pressure drop minimizes system impact, enabling flow control at near-atmospheric pressures and shortening system response times. Alicat’s MCDW brings the benefits of low pressure drop to our incredibly versatile MCD bidirectional flow controller.
Control flows into your flowing or closed process in one direction, and then reverse flow with multivariate measurement of flow, pressure and temperature in each direction. Or control flow into a closed process using pressure control while monitoring flow rates, and then vent the volume with no need for additional bleed valves. We’ll use your application parameters to customize your valve and PID tuning to ensure that it delivers fast and stable control, in both directions.
- Versatile. Control flow with positive pressure or vacuum in one or both directions. Or control pressure into flowing or dead-ended processes. (Download our infographic on the right for flow diagrams.) In all cases, flow measurement is multivariate (mass flow, volumetric flow, pressure and temperature), and you can select another gas calibration on the fly or define your own gas composition with COMPOSER™.
- Connected. Easy integration into your digital industrial network with Ethernet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP) or serial communications options.
- Durable. MCDW series flow controllers can temporarily flow liquids without getting destroyed. For environmental hardiness, we can build your flow controller with IP66 ingress protection.

MCT–Stream Switching Gas Mass Flow Controllers
Stream switching with proportional flow control
Reduce your inventory and clean up your workspace with Alicat’s stream-switching gas flow controllers. Dual valves located upstream allow you to switch your gas source. Dual valves located downstream make it possible to run two separate processes on a single source of gas. We’ll use your application parameters to customize your valve and PID tuning to ensure that it delivers fast and stable control, in all directions.
- Versatile. Use a single gas source for two separate processes, or switch between separate sources for a single process. Select another gas calibration as you switch sources or define your own gas composition with COMPOSER™.
- Connected. Easy integration into your digital industrial network with Ethernet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP) or serial communications options.
- Durable. MCT series flow controllers can temporarily flow liquids without getting destroyed. For environmental hardiness, we can build your flow controller with IP66 ingress protection.
