WebTemperature has a greater effect on gas flow calculations, because gas volume expands with higher temperature and contracts with lower temperature. But similar to specific gravity, temperature affects flow by only a square root factor. For systems that operate between -40°F (-40°C) and +212°F (+100°C), the correction factor is only +12 to -11%. http://blog.dwyer-inst.com/2024/09/06/variable-area-flow-corrections/

Webare correct if the inlet gas pressure is equal to the pressure for which the tube was calibrated. For your convenience, Table 1 provides correction factors for gases other than air at standard conditions. Call a customer service representative if you require further assistance in sizing a rotameter for your particular application. WebDo not use the pressure supplying the rotameter if the valve is on inlet. If your valve is on outlet of the rotameter then either use a pressure correction factor or use a calibration chart corresponding to the pressure in the tube.
