FAQ

Gas Mass Flow - units

Our Sensor-Finder is made to provide a first choice of suitable sensors and uses for simplification general volume flow units [m3/h], [l/min], [ml/min], [ccm/min] without reference conditions (Temperature, Pressure). Normally gas mass flow units are clearly defined as a weight per time unit e.g. [g/min], [kg/h] or often as volumetric unit per time - stating a reference condition for the pressure and temperature.

With the index "N" or "n" (Normal Condtions) or "S" or "s" (Standard Conditions) the volume unit obtains a reference-pressure and reference-temperature. As the definition of Normal- or Standard Conditions depend on country and branch, it is always helpful and recommended to add clear values for the reference-pressure and -temperature.

For our homepage we defined:

  • Standard Conditions: 20°C, 1013,25 mbar (e.g. Sm3/h, Sl/min, SLPM, mls/min, Sccm/min)
  • Normal Conditions: 0°C, 1013,25 mbar (e.g. Nm3/h, Nl/min, ln/min, mln/min)

The difference between Norm and Standard Condition is around 7% calculated by the formula: Sl = (Nl/273,15) x 293,15

Calibration and Adjustment of Gas Mass Flow Sensors

Calibration is defined as the measurement and documentation of the deviation of a tested measuring device (Gas Mass Flow Sensor) against a reference measuring device (Standard) with the known or assigned higher correctness (accuracy). A calibration does not include an adjustment of the tested measuring device.

The adjustment is the process of altering the performance of tested measuring device (Gas flow Sensor) to ensure that the output values it indicates (display, output signal) are correct within its specified accuracy limits.
