Metrological performance and certifications
Accuracy
±2 % of rate or ±2 mm/s (±0.08 in./s) whichever is the
greater
Volume
Refer to ISO 7145-1982 (BS 1042 section 2.2) for details
Flow condition
Fully developed profile in accordance with ISO 7145-1982
(BS1042 section 2.2.)
Maximum flow
The maximum velocity depends upon the actual insertion
length. Typical insertion lengths are 0.125 and 0.5 x pipe
diameter. Figure 26 is a guide* to the maximum allowable
velocity for different insertion lengths.

* Figure 26 is intended as a guide only. Factors that influence the maximum insertion
length into the pipe include: insertion sensor mounting components (for example,
standoffs, bushes and valves) pipeline vibration, fluid vibration and pump noise.
