If “Oil” is selected as flowing fluid the flow meter is using API 2540 equation for

fluid density calculation. Following parameters related to flowing Oil have to be

entered:

Oil Density @ 60 °F (kg/m^3)

Constant K0 (no units)

Constant K1 (no units)

See Richard W. Miller,

Flow Measurement Engineering Handbook (Second Edition,

1989),

page 2-76 for definition and use of the API 2540 equation.

NOTE: If “Oil” was not selected at factory as your process flowing fluid

the default settings for API 2540 equation are made for Crude oils and

JP4 as following:

Oil Density @ 60 °F 898.0 kg/m^3

Constant K0 341.0957

Constant K1 0.0
