Turn-key tabletop dynamic gas mixer with integrated 6 button TFT color interface, removable Bluetooth® tablet, powered docking station, and pre-loaded Fusion Flow MXM software.

Configurable chassis allows for 2 to 6 gas inputs with any combination of flow rates ranging from 100 SCCM to 100 SLPM full-scale, per channel.


MXM-TAB at a glance

Custom engineered for every application, the MXM family of gas mixers are the only hardware-based blenders of their kind to offer both flow and pressure delivery modes. Accurate and dynamic gas mixing is accomplished via specially tuned Alicat Scientific mass flow controllers commanded by our proprietary MixModule device. The included Microsoft Windows Surface Pro tablet with pre-loaded Fusion Flow MXM software gives the user full control over the gas mixing process, including preset recipes, automation steps, and robust data logging. Wireless connectivity allows remote access to the MXM-TAB base unit, making it ideal for active research laboratories or installations requiring physical separation from the gas mixing hardware.

Human Interface

The MXM-TAB is a turn-key tabletop dynamic gas mixer with a dedicated 6 button TFT color interface and Windows based high resolution tablet. An articulating, fully featured docking station creates a PC-like user experience, provides a host of modern connectivity options, and charges the tablet. Using the the included Bluetooth module, the tablet can be removed and used up to 200 feet away from the MXM base unit.



The ‘business end’ of the MXM-TAB showcases the 6 available source gas input ports and the single mixed gas outlet port. Either ¼” or ⅜” tube compression fittings are used depending on the chosen mass flow controllers. Additional connections include: RS232 male DB9 for bi-directional communication, 24VDC 4 pin DIN power port, 4 pin locking connector for additional or custom wiring features, 8 pin M12 port for powering outboard pressure or flow devices, Bluetooth® antenna, and the master power switch. The tablet docking station adds four USB 3.0 ports, one USB-C port, RJ45 Ethernet, DisplayPort++ and HDMI external monitor connections.

Form Factor

A small 14”x14” footprint allows the MXM-TAB to act as a bench top gas mixer, to be installed on a cart, or easily transported for use ‘on-site ‘ via its included Pelican™ transit case. Note the stainless steel chassis and handles, powder coated steel cover, and rubber feet allowing it to be placed on any surface or mounted in any orientation. With the included communications cables, the articulating docking station can be placed up to 6 feet away from the MXM base, to accommodate any use-case scenario.

  • 500 SCCM—50 SLPM
  • 1SLPM—100 SLPM


Accuracy at calibration conditions for individual gas control channels:

  • Gas control channels with full scale ranges from 100 SCCM to 20 SLPM: ±0.6% of reading or ±0.1% of full scale, whichever is greater
  • Gas control channels with full scale ranges from 50 SLPM to 100 SLPM: ±0.8% of reading and ±0.2% of full scale


Repeatability (2σ) for individual gas control channels:

  • Gas control channels with full scale ranges from 100 SCCM to 20 SLPM: ±(0.1% of reading + 0.02% of full scale)
  • Gas control channels with full scale ranges from 50 SLPM to 100 SLPM: ±(0.2% of reading + 0.02% of full scale)


Typical control response time for individual gas control channels:

  • As fast as 25 ms; flow rate, gas species, and back-pressure dependent
  • Proprietary, matched-tuning procedure performed on each MFC according to the application parameters


*Custom ranges and alternate units of measure are available at no extra charge, however density based, true-mass units of measure are not possible at this time (e.g. lbs/hr, kg/min, etc.)

  • Each MXM-PC system is custom engineered to best serve a specific application, even if the application is generic in nature (e.g. general, unspecific laboratory use). Up to 6 internal MFCs can be specified, but they don’t all have to be connected to unique gases. Any channels set to the same gas will be treated as a unified operational group. This allows for doubling or tripling of flows within the chassis, if more than 100 SLPM is needed for a particular gas, for example. Similarly, this also allows for high dynamic range capabilities if both high and low flow devices are used for the same gas (the MXM-PC will chose which MFC or MFCs to use based on the immediate need, for best accuracy and control). In most cases, the installed gas channels can be configured to measure and control any one of the 98 built-in gas models, making the MXM-PC an extremely flexible gas blending platform.
  •  The MXM-PC has many user configurable mixed gas delivery modes to accommodate almost any process:
    • Mass flow with no start/stop pressure limits
    • Mass flow with lower start pressure limit and/or upper stop pressure limit
    • Mass flow with total volume limit (with or without pressure limits) 
    • Active pressure control with no start/stop pressure limits
    • Active pressure control with lower start pressure limit and/or upper stop pressure limit
    • Active pressure control with total volume limit (with or without pressure limits)
    • Option to cease all automated mixing operations if any limits are reached (single-shot mode)
    • Option to reset the volume totalizer upon any stoppage event
  • A locking 4 pin electrical connector on the rear of the unit allows for remote EMO triggers, remote 24V alarm output, and 3rd party analog analyzer input for  monitoring and alarming on the gas mixture concentration (user configurable)
  • M12 connector for attaching a precision outboard process controller (e.g. Alicat ultra low-flow MFC, or specialized pressure controller)

Some of the process attributes which are taken into account during the application engineering phase are:

  • Identifying all of the source gas species to be blended (whether pure, pre-mixed, corrosive or non-corrosive)
  • Feed pressures available for each gas
  • Gas mix ratio(s), recipes or dilution levels desired
  • Expected volume, plumbing, and restrictions downstream of the gas mixer
  • Total mass flow rate(s) required
  • Outlet pressure(s) required
  • Required delivery mode feeding the process
  • Any environmental/automation/industrial integration considerations
  • 4 in/4 out digital I/O USB module (for exclusive use with the MXM software)
  • 4 in/2 out analog I/O USB module (for exclusive use with the MXM software)
  • Stainless steel ballast cylinders (150cc, 300cc, 500cc, 1L, 2L, 5L)
  • Stainless steel static mixing tubes (¼”, ⅜”)
  • High accuracy speed of sound binary gas analyzer for 2 component gas mixtures (integrated or outboard options)

Unit ships in a re-usable, hand-fitted foam Pelican transit case, allowing the MXM-PC to arrive safely from our factory, and also be easily transported in the future.

Advanced Gas Mixing Made Easy

Included Fusion Flow MXM Command and Control Software

All MXM variants can mix gas autonomously. At the core, this platform is a hardware based gas blender, requiring neither computer nor software to operate. However, the functionality of the MXM can be greatly enhanced by the use of Fusion Flow’s command and control software, included with the MXM-TAB system.
Users choosing to operate their MXM through the software gain the ability to save unlimited gas mix recipes, log all gas mixing data, run automation scripts, program conditional based events, and utilize the optional analog and digital I/O boxes.
Coded for use with any MXM system, this Windows 10/11 based software package communicates directly (and solely) with the Fusion Flow MixModule device; whether it’s inside of the MXM chassis or out in the open as in a stand-alone MXM-SA system. Please note that the MXM software only works with the Fusion Flow family of gas mixers utilizing the MixModule brain; it cannot be used with individual MFCs in a direct control capacity.
