Atec Panametrics-Olympus-PT868 - Manual (Page 5)

Energy Accuracy:
The accuracy of the energy
measurement is a combi-
nation of the accuracy of
the associated flow and
temperature measurements.
Transit-Time Mode:
1% of reading typical for
calibrated systems.
TransFlection Mode:
2% of reading typical for
calibrated systems.
Fluid Types:
Transit-Time Mode:
Acoustically conductive fluids,
including most clean liquids
and many with entrained
solids or gas bubbles. Maxi-
mum void fraction depends
on transducer, interrogation
carrier frequency, path length
and pipe configuration.
TransFlection Mode:
Multiphase fluids, including raw
sewage, sludge, slurries, tar
sands, oil-water-gas mixtures,
acoustically attenuating
liquids and other demanding
applications.
