4.1.3 Flow Accuracy (Velocity)
±0.5% of reading (achievable with process calibration)
Accuracy specifications assume a fully developed flow profile and a straight run of 10 pipe diameters upstream and
5 pipe diameters downstream.
Typical Clamp-On Flow Accuracy (Velocity)
Pipe Diameter (ID) > 6 in. (150 mm): ±1% to 2% of reading
Pipe Diameter (ID) <
6 in. (150 mm): ±2 to 5% of reading
Typical Wetted Flow Accuracy (Velocity):
±1% of reading
Note: Accuracy depends on pipe size, installation and whether measurement is one-path or two-path.
4.1.4 Range
Transit-Time Mode:
-40 to 40 ft/s (-12.2 to 12.2 m/s)
4.1.5 Rangeability (Overall)
400:1
4.1.6 Repeatability
±0.1% to 0.3 of reading
4.1.7 Energy Accuracy (% of Reading)
The accuracy of the energy measurement is a combination of the accuracy of the flow and temperature measurements.
Transit-Time Mode:
Accuracy of 1% is typical for calibrated systems
Note: Above specifications require a straight run of 10 pipe diameters upstream and 5 pipe diameters downstream.
4.1.8 Fluid Types
Transit-Time Mode:
Acoustically-conductive fluids. This includes most clean liquids and many with entrained solids or gas bubbles (the
maximum void fraction depends on the transducer, interrogation carrier frequency, path length and pipe configuration).
