7.2 Gas Data Menu
This menu shows the current Reynolds number used by the flow meter to implement flow
profile compensation, as well as operating pressure and temperature and computed gas
properties.

Table 7- 4 Gas Data Menu Items
TEMP 1 Measured temperature from Channel 1 RTD.*
TEMP2 Measured temperature from Channel 2 RTD.
Reynolds Number The flow meter corrects the current flow rate in accordance with this Reynolds number.
This number is determined from pipe ID, current flow rate and gas kinematic viscosity.
Specific Gravity Actual specific gravity of gas computed as follows: molecular weight of gas divided by
molecular weight of air.
Base S.G. Specific Gravity measured at base temperature.
Temperature Measured temperature (Analog input or from RTD input.)
Pressure Measured pressure (Analog input or from Gas Parameters menu.)
Volume Corr. Flow rate/total multiplier used to correct the measured volume to standard volume.
Viscosity Kinematic viscosity of gas.
* If the analog input for temperature is enabled it will override the internal RTD temperature measurement and TEMP1 will
reflect the analog input temperature instead. For Dual Path operation only TEMP1 is used for volume correction.
