Overview
Fast mass flow controllers and mass flow 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.
CODA Coriolis Mass Flow Meters and Controllers
Open in new windowHigh precision liquid and gas measurements independent of fluid composition.
Alicat’s new series of Coriolis instruments offers direct mass flow measurements for exceptional accuracy in a broad array of precision ultra-low flow and high pressure applications. CODA mass flow meters and controllers are compact and pair fast response times with exceptional zero stability to create an industry leading precision instrument. Designed to be highly insensitive to external vibrations, our Coriolis units provide unwavering accuracy throughout the 0.08 g/h to 100 kg/h measurement range.
- Versatile. Even when you don’t know the chemical composition of your fluid, CODA enables you to obtain accurate readings of mass flow rate for both liquids and gases. This makes CODA ideal for applications with changing or unknown fluid compositions.
- Accurate. Measure flows with NIST-traceable accuracy for liquids and gases down to 0.05% of the full scale flow rate. Our Coriolis instruments are also highly insensitive to external bumps and vibrations, ensuring accurate measurements despite environmental interference.
- Robust. CODA covers more applications for you with resistance to corrosive fluids, an IP67 rating, and operating pressures up to 4000 PSIA. All-metal seals are additionally available with our CODA meters.

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-Series 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.

Open in new windowAlicat’s liquid flow controllers and meters provide accurate measurement and stable control across a wide range of applications. Our Coriolis mass flow instruments can accurately measure and control liquid flow rates up to 100 kg/h even when flowing aggressive liquids and mixtures of unknown composition. When flowing water or other common non-corrosive liquids, our laminar liquid flow instruments can provide real-time measurements and control of process pressure and temperature, with an optional batch processing feature to simplify process control.
From distillation and electrolysis to additive dosing and water treatment, Alicat liquid flow instruments ensure fast, accurate measurement and control of your process.

Direct Mode connects the Alicat FP-25 directly to your sampler’s downtube. The pass-through connection most closely replicates sampler operating conditions. The low pressure drop of the Alicat ensures that it is virtually invisible to your air sampler.
- Thread the Direct Mode downtube adapter into the outlet of the FP-25 until its face seal is tight against the flow body.
- Thread the Direct Mode PM inlet adapter into the inlet of the FP-25 until its face seal is tight against the flow body.
- Fit the FP-25 onto the BAM downtube, and place the PM10 inlet on top of the FP-25. If using a PM2.5 cyclone, leave it in place, and fit the FP-25 between it and the PM10 inlet.
- Insert the FP-25 external temperature probe into the sampler’s radiation shield.
- Be sure to tare the Alicat FP-25 before you begin the BAM 1020 or BAM 1022 flow calibration.

PCU–Series: Gas Flow Portable Calibration Unit
Portable flow calibration with a very wide dynamic range.
Order Directly from Alicat
When a single flow meter won’t cover all of your calibration needs, consider using a portable calibration unit (PCU). 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. PCUs can be powered by 4 AA batteries or the included AC/DC power supply adaptor.
- 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™.
- Rugged. The PCU houses the flow meters within a rugged hard case and can withstand drops if they should occur.
PCU’s are also available in our Whisper™ configuration with low pressure drop (PCUW-Series) and 316L configuration for use with corrosive gases (PCUS-Series).
Example Application shown with 2 Alicat components sold separately.

MCD–Series: 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.

MCDW–Series (Whisper™): Low Pressure Drop Bidirectional Gas Mass Flow Controllers
The most versatile gas flow controller, with minimal system impact.
Order directly from Alicat
Whisper™ 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.

Order Directly from Alicat
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™.
