Appendix A. Specifications and model
configurations
A.1 Operation and performance
Fluid Types
Liquids: acoustically conductive fluids, including most clean
liquids, and many liquids with small amounts of entrained
solids or gas bubbles. Maximum void fraction depends on
transducer, interrogation carrier frequency, path length, and
pipe configuration.
Flow Measurement
Correlation transit time technique
Accuracy
• ±1%: >=2 in pipe; greater than 1 ft/s velocity
• ±2%: <=2 in pipe; greater than 1 ft/s velocity
Accuracy statement assumes measurement of a
single phase homogenous liquid with a fully developed
symmetrical flow profile passing through the meter
(typically 10 diameters upstream and 5 diameters
downstream of straight pipe run). Applications with piping
arrangements (e.g. two out of plane elbow at upstream)
that create an asymmetrical flow profile may require
extended piping straight runs and/ or flow conditioning for
the meter to perform to this specification.
Calibration
All meters are water calibrated and include a calibration
certificate.
