Flow Measurement Devices



Overall, the team was most impressed by the first and second devices. Both contain two groups of sensors
on either side of a resistive sieve arranged in the gas channel and lose almost no flow making them precise
pieces of instrumentation.
However, 14026's design borrows most heavily from the fourth, since it is something the team could likely
replicate and improve upon at a modest price.

Risk Assessment

Team 14027 maintains a Risk List which details possible failures and the predetermined correct course of action in each circumstance.
The team revisits and updates these risks every three weeks to ensure that they remain fresh in the minds of team members.

System Reviews

Week 3: Problem Definition Review

The Week 3 Review gave Team 14027 the opportunity to show the customers their understanding of the Project Readiness Package
and to ask for their input.

Following the presentation, the customers provided feedback, stating that the team was on the right track. They did, however, caution
the team not to restrict themselves to a device, but to also be open to the idea of creating a process.

Week 6: System Design Review

The Week 6 Review allowed the team to show their ideas for different forms of their project. The presentation highlighted the conceptual
aspects of the design problem, checking for feasibility without attempting to go straight into solutions.

The customer was again asked for, and provided feedback based on what they saw. The feedback was largely positive, with the customer
expressing some concern regarding software and data storage capabilities, as well as possible issues with sensor signal delays. The
team resolved to make signal timing an integral part of planning.
