Appendix A. Specifications
A.1 Overall 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
Flow measurement: Correlation Transit-Time™ mode
Pipe sizes: 0.5 in. (15 mm) or greater
Pipe materials: All metals and most plastics. Consult Panametrics for concrete, composite materials,
and highly corroded or lined pipes.
Accuracy: ±1% of reading in application, for ≥2 in. (50 mm) pipe and >1 ft/s (0.3 m/s) velocity ±2% of
reading in application, for <2 in. (50 mm) pipe ? and >1 ft/s (0.3 m/s) velocity ±0.5% in
field calibration
Note: Installation assumes a fully developed, symmetrical flow profile (typically 10
diameters upstream and 5 diameters downstream of straight pipe run). Final
installation accuracy is a function of multiple factors including fluid,
temperature range, pipe centricity and others.
Calibration: All meters are water calibrated and delivered with a traceable calibration certificate.
Repeatability: ±0.2% of reading
Range
(bidirectional):
-40 to +40 ft/s (-12 to +12 m/s)
Rangeability
(overall):
400:1
Measurement
parameters:
Velocity, volumetric, and totalized flow
