are free from damage due to process, ambient or other
abnormal conditions.

Internal components: rotor, upstream to downstream
cone, etc.
•
Meter body housing, external flanges, flamepath.
•
Bolting
•
Electrical connections.
Use a non-toxic metal cleaning solvent.
Do not use common petrochemical solvents like Benzene,
Toluene or Xylene as they can pose potential health hazards.
A careful review of turbine meter proving history, such as
turbine meter factor control charts, can reveal potential
problems with turbine meter measurements. Examples
include bearing drag due to wear or an increased internal
cross-sectional area due to erosion.
