Meter Technology Selection

Turbine: Good linearity, requires flow conditioning, affected by viscosity changes
Coriolis: Direct mass, measures density, minimal flow conditioning needed
PD: Excellent low-flow performance, requires clean fluid, higher maintenance

Engineering Notes

Back pressure: Must exceed EVP + meter ΔP + safety margin to prevent flashing
Straight runs: Turbine meters need 10D upstream (20D without conditioner)
Proving: API requires ±0.02% repeatability for custody transfer
Sampling: ISO/GPA standards require isokinetic sampling for mixed products
