Available base flow range scales for individual gas control channels (any combination of 2 to 6 channels)*:

• 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 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 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 an extremely flexible gas blending platform.
•  The MXM 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 3^rd 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

• Fusion Flow MXM command and control software for Microsoft Windows 10 or Windows 11
• 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)
