In order to make an intrinsically volumetric device useful for measurement of gases, it is generally necessary to adjust the readings to a standardized temperature and pressure, yielding mass flow. For this reason, we include temperature and pressure transducers to allow computation of standard (mass) flow by the internal computer (Figure 2).
