2 Ultrasonic Flowmeter Series 6 gas flow meter
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
plus
.

2.4 Calibration
When using the Ultrasonic Flowmeter Series 6, model Q.Sonic
plus
in custody transfer applications, most countries demand (by law) a calibration from a certified calibration institute, supervised by an inspector of weights and measures. Examples of facilities generally used for calibrations are Euroloop in Rotterdam (NL), TransCanada Calibrations in Canada and PIGSAR GH45 of E.ON Ruhrgas AG in Dorsten (D). If the Q.Sonic Series 6 has to be in accordance with MID, extra restrictions should be taken into account (see chapter 9.4).

3 Theory of operation
An ultrasonic flow meter is an inferential measurement device that consists of ultrasonic transducers that are typically located along a pipe's wall. The transducers are inserted into the piping using a gas tight mechanism. Ultrasonic pulses are alternately transmitted by one transducer and received by the other one. Figure 3 shows a simple geometry of two transducers, ‘A’ and ‘B’, at a sharp angle “ϕ” with respect to the axis of a straight cylindrical pipe with diameter “D”. The Q.Sonic Series 6 employs reflection paths, where the acoustic pulses reflect one or more times off the pipe wall.

Figure 3: Ultrasonic measuring line
3.1 Flow velocity measurement
The acoustic pulses are crossing the pipe like a ferryman crossing a river. Without flow, they propagate with the same speed in both directions. If the gas in the pipe has a flow velocity different from zero, pulses travelling downstream with the flow will move faster, while those travelling upstream against the flow will move slower. Thus, the downstream travel times “tab“ will be shorter, while the upstream ones “tba“ will be longer as compared when the gas is not moving. Equation 1 illustrates the computation of these times:

Ln the straight line length of the acoustic path between the two transducers. VoGraw is the average uncorrected (raw) gas velocity.
ϕn the angle between the gas flow and ultrasonic signal.
The raw gas velocity is corrected by a Reynolds flow profile correction. This correction is depending on the path type. Also the contribution of the gas velocity of each path to the combined gas velocity is depending on the path type.

3.2 Correction after calibration
After flow calibration the meter can be adjusted either through an adjust factor or through linearization. How the meter is adjusted can be visualized at the display (see chapter 6.1).
