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.

Stopping an operational process for validation or calibration is a necessary evil. Alicat’s portable flow calibrators make this procedure more palatable by reducing the downtime and disruption to your process. Instant-on and real-time readings for multiple gases across wide flow ranges let you get in and out quickly.
- Accurate. Calibrate flows with NIST-traceable accuracy for a variety of gases down to 1/10,000th of full scale, or define your own gas composition with COMPOSER™.
- Efficient. As soon as you power the MB on, it’s ready to display live flow, pressure and temperature readings in your choice of engineering units.
- Tough. MB series portable flow meters are designed to be carried and can withstand drops if they should occur.

Alicat’s PCU is a secondary calibration standard that combines up to 3 high-accuracy flow meters of varied ranges (max 500 slpm) with totalizers into a rugged industrial carrying case for go-anywhere portability. PCU’s can be powered by 4 AA batteries or the included AC cable and include a copy of Alicat’s Flow Vision SC™ software.
- Versatile. Quickly calibrate multiple instruments across a combined turndown range of up to 100,000:1 (for example 5 sccm – 500 slpm) with easy push-connect fittings or optional compression fittings.
- Accurate. Measure live flow rates and flow totals with NIST-traceable accuracy (as good as 0.5% reading) for a variety of gases down to 1/1000th of full scale, or define your own gas composition with COMPOSER™.

MCD–Bidirectional Gas Mass Flow Controllers
Versatile bidirectional flow controller.
Order Directly from Alicat
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. Backed by annual recalibrations and our limited lifetime warranty, an Alicat instrument will keep your process running smoothly, even in challenging environments, for years to come.

Automated Leak Testing with Bidirectional Flow Control
Set the MCD to control absolute pressure, and you have a basic leak-check system in a single device. Once the test pressure is achieved, a positive flow rate indicates the presence of a leak. The second valve is used at the start of the test to ensure the target pressure is not overshot, and at the end of the test to release the pressure.
Testing and Characterization of a Pressure Relief Valve
The MCD bidirectional flow controller sets a constant mass flow rate against the pressure relief valve as the absolute pressure in the system is recorded. After the relief valve opens, a negative flow setpoint is commanded to reduce the pressure and prepare for another run.

Bidirectional Flow vs Pressure Characterization for Respiratory Devices
Mimic human respiration with bidirectional flow control into and out of a respiratory device at flow rates consistent with the range of breathing. A low pressure drop “Whisper” configuration (MCRDW) also allows the flow controller to “breathe” slowly with minimal pressure applied.
Bidirectional Flow Control for Remote Air Sampling and Calibration
Sample ambient air with a vacuum pump in one direction, and then periodically calibrate your gas analyzer with positive pressure in the other direction, all without disconnecting any part of the system. A low pressure drop “Whisper” configuration permits volumetric flow sampling at the standard 16.7 lpm flow rate. This makes possible the operation and calibration of remote air monitoring stations without human intervention.

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. Backed by annual recalibrations and our limited lifetime warranty, an Alicat instrument will keep your process running smoothly, even in challenging environments, for years to come.

Valve Options
Your mass flow controller may be customized with one of the following valving options to ensure optimal performance under your expected process conditions.
- MCT – small proportional control valve for flow ranges of 20 slpm and below
- MCT with PCA designation – high-performance proportional control valve used for some applications with higher pressures
- MCPT – small proportional control valve with the largest orifice (not available for corrosive configurations)
- MCRT – nearly frictionless large Rolamite proportional valve for flow rates of 50 slpm and above
Corrosive Gases (MCTS series)
Instruments in the standard MCT series are also available with an optional “S” configuration (MCTS) for use with corrosive gases. In this configuration, we upgrade the valve to 303 stainless steel, the sensor to 316L stainless steel and the elastomers to FFKM. Some corrosive gases require 316L stainless steel throughout the flow path, and in this case we can upgrade both the valve (type PCA) and flow body to 316L for full-scale flow ranges of 20 slpm or less.
Build Options
- Communications protocols (analog, RS-232, RS-485, DeviceNet, EtherCAT, Ethernet/IP, Modbus RTU or TCP/IP, PROFIBUS)
- Displays (monochrome or color, integrated or panel-mount)
- Process connections (NPT, SAE, AN, BSPP/G, welded compression or VCR/VCO fittings)
- Elastomers (Viton, FFKM, EPDM, Silicone)
Alicat’s MCT series uses small proportional valves for control at lower flow rates and is suitable for use with non-corrosive gases.

Continuous Operation of a Bottle-Fed Process
In the upstream configuration, you can use an MCT to continuously operate a bottle-fed process. When the bottle pressure drops below your threshold, simply switch your input to the other stream and its full bottle. As that bottle feeds your process, you can exchange the emptied bottle on the first stream for a fresh one.
Multi-Source Calibration of an Analyzer
Calibrate a gas analyzer that measures concentrations of pollutants in ambient air with stream-switching at the inlet. Three separate calibrated bottles of air and greenhouse gas mixtures lead to the three inlet valves of an MCT. An additional proportional valve on the outlet side controls the flow rate of each stream when it is needed by the analyzer.
Feeding Multiple Analytical Processes from a Single Source
In the downstream configuration, an MCT can be used to feed two wholly separate analytical processes from a single source of gas. You could sample ambient air and send it to two separate analyzers on an alternating schedule. Or you could supply two separate processes from the same bottle of nitrogen, each with fully proportional flow control.
