On the basis of its 4-Beam ultrasonic technology, the F706 is capable of providing such solutions for liquid hydrocarbon products as well as any other liquid medium. Being completely drift-free and detecting even the smallest flow rates, it is the ideal meter for leak detection purposes.
The F706 non-invasive flow meter can be placed next to a custody transfer meter for continous validation. Moreover with the F706 in place, downtime can be avoided in case the custody transfer meter is temporarily taken out for recalibration.
With its 4 beams, in reflect mode providing 8 paths through the gaseous medium, the meter averages the result of up to 4 planes. This arrangement averagesout cross-flow and achieves the optimum non-invasive compensation. On longer straight runs, the 4-Beam meter achieves outstanding accuracy performance due to the individually averaged path effects and can thus be used for redundancy measurements of custody transfer meters or leak detection.
Temperature compensated transducers, unique digital signal processing with superior noise suppression combined with a highly rugged design care for an unrivalled degree of reliabilialy, durability and accuracy - ensuring perfect operation of the system under the harshest field conditions and makes it even suitable for installations buried in the ground (IP68 / NEMA 6P rated).
The F706 is capable of accuracy in the Custody Transfer class. By measurement principle, non-invasive ultrasonic flow meters will contain some uncertainty due to uncertainties in the pipe wall thickness. These can be minimized with careful installation and precise pipe wall measurements. While an installed “out of box” custody transfer accuracy is not possible, in many pipeline services like check-metering, leak detection and others, it is possible to calibrate the G706 meter in-situ to achieve Custody class accuracy (proven by industry independent Calibration Facilities - test reports are available upon request).
When creating a new flow measurement point, a significant part of the costs are incurred by the installation work (line shut-down, pipe cutting, pipe flushing, etc.). These costs are significantly reduced using the F/G706 clamp-on technology that requires zero impact on pipe integrity while commissioning.
