Nitrogen Primary Plasma Gas Flow Correction Calculator
The following calculators convert plasma gas flow values for the Metco 7M and 3M systems between:
Metco Flow Meter Reading (FMR)
SCFH (Standard Cubic Feet per Hour(700F)
L.P.M (Litres per Minute under same conditions as SCFH)
NLPM or SLPM (Normal Litres per Minute (0oC)
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.
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.
