From the iPhone/iPad main screen, select “Settings” and find iMixer in the list of installed apps.

 

Cost calculations are performed using either a “Shop” set of values or a “Retail” set of values. The cost of a fill is calculated by multiplying O2, Helium, and Top Off Mix costs by the number of cubic feet of each gas used plus the blending fee. 

 

Calculations can be in either imperial or metric units. If the Imperial calculation switch is set to “off”, all calculations are done in metric units.  Costs must be specified in the default units.  If Imperial is “on”, O2, Helium, and Top Off Mix costs are per cubic feet; otherwise they are by cubic liter.

 

When the Real Gas switch is set to "on", van der Waals equation is used to calculate blending plans.  When set to "off", ideal gas calculations are used.  The Real gas temperature default is the temperature of the cylinder during filling.  Volume is the internal volume of the cylinder.  This value can be obtained either from the cylinder manufacturer or closely approximating it using a formula.  A cylinder with radius r units and height h units has a volume of V cubic units given by v= πr2h.  A standard Aluminum 80 has an internal volume of 0.3929 FT3 (11.13L3).  The van der Waals equation is not terribly sensitive to these parameters so an approximation is generally good enough.

 

Fill O2 First determines the default order gas is added during the mixing process.  If Fill O2 First is set to “on” the default mixing procedure is to add Oxygen first, then Helium, then the Top Off Mix.  When set to “off”, Helium is added first followed by Oxygen and then the Top Off Mix.

 

The Doubles Switch determines if cost calculations are done for either singles or doubles. When set to “on”, calculations are for doubles by default.

 

When the Retail Switch is set to “on”, iMixer uses the retail values cost set to determine fill cost. When set to “off”, the shop cost value set is used.

 

The value Max PO2 is the partial pressure of Oxygen used in the maximum operating depth calculation.

 

Bank gas and Top off gas can be any mix (Air, Nitrox, or Trimix). The default is to top of with air.

 

Cylinder Specifications refer to the characteristics of the tanks you are filling. In this example, the default cylinder is a standard Aluminum 80 containing 80 FT3 of gas with a working pressure of 3000 PSI. This volume refers to the quantity of gas in the cylinder when filled to it’s working pressure; and not the volume used for real gas calculations (which is the internal volume of the cylinder when empty).  If default calculations are in metric units, the default volume and working pressure should be in metric units as well. In this example, the cylinder would be 206 BAR and the working pressure set to 2265 liters.

 

In order to make your default cylinder a high pressure steel 120, you can set these values to 3500 and 120 respectively.  These values control the calculation of the volume of gas used in a fill which directly impacts price.

 

The Default Starting Mix is what is in your tank when you start blending. Default Target Mix is what you want to end up with.

 

All defaults can be overridden in the iMixer app with the exception of the Shop and Retail Cost Set values.
