Airbus A380 Minisonic Clamp On

Background:
AIRBUS had a requirement to measure fuel flow within the fuel supply system on a full scale fuel test rig to model the fuel distribution during the refueling process. This modeling is important so that refueling times can be assessed and improved and individual fuel tanks can be monitored.
The Problem:
From the outset the requirement was for a completely non intrusive system so that the actual measurement did not affect the actual fueling process by the creation of back pressures as would be found with mechanical systems (i.e. Turbines, Pitots etc.). Also the system had to have ATEX certification to Zone 0 as JET-A1 would be used after the initial testing with water.
The Solution:
The MINISONIC 600 was offered as a completely non intrusive system, offering measurement where other systems would have had an effect on the fuel distribution. It was supplied in two forms, the first a single channel system where one converter measures the flow in one pipe, the other was a 2 channel system where one converter measures the flow in 2 separate pipes. The measurement system had to be rated ATEX ZONE 0 The MINISONIC range of flowmeters were also selected for their range ability and ease of installation. Where pipework has been installed, clamp-on meters can be selected for their retrofit capability. Flows are not interrupted or by-passed and the installation can be easily checked by the in-built diagnostics.Temperatures to 180 C are a standard option (and now down to -50 C) pipe sizes of 10-3300 mm are offered through firmware and sensor options. 2 channel and a 2 chord versions are available. The ‘ESC’ autofocus function increases the performance of the meter in extreme conditions.
