Process conditions
Used to calculate the density ratio. Refer to the equation listed under Density Ratio.
Process temperature
Process Temperature is the absolute temperature T
f
at actual (flowing) conditions in
degrees Rankine or Kelvin. The flowmeter electronics will convert from degrees Fahrenheit
or degrees Celsius to degrees Rankine or Kelvin respectively.
Process pressure
Process Pressure is the absolute pressure P
f
at actual (flowing) conditions in psia or KPa
absolute. The flowmeter will convert from the pressures in absolute for the calculation.
Process compressibility
Process Compressibility is the compressibility Z
f
at actual (flowing) conditions (dimension-
less).
Base conditions
Base Conditions is used to calculate the density ratio. Refer to the equation listed under
Density Ratio.
Base temperature
Base Temperature is the absolute temperature T
b
at standard (base) conditions in degrees
Rankine or Kelvin. The flowmeter electronics will convert from degrees Fahrenheit or
degrees Celsius to degrees Rankine or Kelvin respectively.
Base pressure
Base Pressure is the absolute pressure P
b
at standard (base) conditions in psia or KPa
absolute. The flowmeter will convert from the pressures in absolute for the calculation.
Base compressibility
Base Compressibility is the compressibility Z
b
at standard (base) conditions (dimension-
less).
4.4.4
Sensor
Pipe I.D.
The Pipe I.D. (inside diameter) of the pipe adjacent to the flowmeter (mating pipe) can
cause entrance effects that may alter flowmeter readings. Specify the exact inside diameter
of the pipe to correct for these effects. Enter the appropriate value for this variable.
