7.8
Setting Thermal Coefficient and Modulus of Elasticity
Introduction
This operating system includes routines that will compensate the measured raw flow rate for
dynamic changes in the pipe dimensions, caused by variations in line temperature and
pressure supplied to the flow meter. To account for variations in pipe material, two data entry
items (Thermal Expansion Coefficient and Modulus of Elasticity) are provided in the Pipe
Data menu screen (see sample menu screen below).
The equation used to automatically compute the change in pipe inside diameter is:

Where:
d
0
= inside diameter of pipe at STP
d
1
= inside diameter of pipe after temperature and pressure change
w = pipe wall thickness
T

and P
0
= Standard temperature and pressure
T

and P

= Operating temperature and pressure
α = Coefficient of Thermal Expansion of Pipe material
E = Modulus of Elasticity of pipe material
