2.1
General
The Ultrasonic Flowmeter Series 6 is a sophisticated, multi-path ultrasonic gas flow meter
manufactured by Elster NV/SA. It has been specifically designed for custody transfer
measuring applications that demand a high degree of accuracy and reliability.
2.2
Applicable standards
The Ultrasonic Flowmeter Series 6 is manufactured to be in accordance with European
Directives: ATEX, PED, EMC and optionally MID.
If the meter is ordered for use at a location where European Directives are NOT mandatory,
the meter can alternatively be manufactured with IECEx or FM approval for use in
hazardous area.
2.3
Configuration
On the flow cell of an Ultrasonic Flowmeter Series 6 several pairs of transducers are
mounted. Each pair of transducers represents one individual measuring path. There are two
measuring path types on the Ultrasonic Flowmeter Series 6: Axial (single bounce) and swirl
(double bounce) these are shown in Figure 1.
Figure 1: Path types
The Q.Sonic
plus
path layout consists of 2 axial paths and 4 swirl paths. This combination
results in a complete symmetrical path layout, ensuring the most optimal accuracy. Figure 2
shows the path layout of the Q.Sonic
