KEP ES749 - 6.8 FLOW INPUT

ES749 Flow Computer
50
Enter the thermal expansion coefcient for a generic liquid. The
coefcient is required for the temperature compensation of volume
with various ow equations (i.e. Liquid Mass or Corrected Liquid
Volume).
Input:
Number with oating decimal point: 0.000...100000 (e-6)
The thermal expansion coefcient can be calculated as follows:
