Plasma Gas Flow Correction / Conversion Calculator

The following calculators convert plasma gas flow values for the Metco 7M and 3M systems between:

Metco Flow Meter Reading (FMR)
S.C.F.H (Standard Cubic Feet per Hour)
L.P.M (Litres per Minute under same conditions as S.C.F.H)
S.L.P.M (Standard Litres per Minute (0^oC))

To use the calculators simply enter a value you wish to convert into the appropriate field and press the "calculate" button. All results shown will be related to a single Metco flow rate reading (FMR). Press "Reset" button to clear the results ready for the next calculation. Alternatively, you can press the "Correction Factors" button without entering data.

Calculators:

Argon Primary Plasma Gas Flow Calculator

Nitrogen Primary Plasma Gas Flow Calculator

Helium Secondary Plasma Gas Flow Calculator

Hydrogen Secondary Plasma Gas Flow Calculator (wide bore nozzle)

Hydrogen Secondary Plasma Gas Flow Calculator (narrow bore nozzle)

Notes:

To calculate the hydrogen secondary gas flows you need to know the primary argon flow rate. Values for hydrogen flow rate when using nitrogen primary gas has not been evaluated yet, but the calculators should give a reasonable approximation. The values obtained for hydrogen should be treated as approximate as system back pressures may vary slightly from unit to unit.

To use the measurement conversion calculators simply enter a number value into the desired field and click calculate. All results shown will be equivalent values. Values are given to seven significant figures ( the odd result may show 9's or 0's over running). Values of 10 000 or greater will be displayed in the e-format e.g. 2.3456e7 which equals 2.3456 x 10⁷ or 23 456 000. Values lower than 0.001 will be displayed in the e-format e.g. 2.3456e-5 which equals 2.3456 x 10^-5 or 0.000 023456. The calculators require that your browser has java script enabled. View all measurement unit conversion calculators on the same page (may not work with all browsers; requires Iframe).
