A power plant was experiencing a feed water flow problem. The issue was on a line
with static pressure exceeding 1000 psi which fed water to one of their steam generators.
The plant’s engineers suspected that it may be an issue with a filter, a flow nozzle,
or even with the line itself, but couldn’t know for certain until they could isolate and capture one of the transient events. Logging differential pressure—so that they could
record readings on both sides of the suspected problem areas—would be the best way
to troubleshoot the issue. But that method was initially dismissed by the team, as the
cost for a unit to measure differential pressure under so much static pressure would be
very expensive.
Crystal Engineering had the solution with the
nVision reference recorder.
