Stability
The stability level is an indication of the consistency of flow reading, as
derived from the combination of signal strength and statistical fluctuations
of the flow reading. A high level of stability would point to a low-noise
environment, clean and optimum acoustic pipe conditions, and a relatively
laminar liquid flow within the pipe. However, the stability level does not
necessarily indicate the accuracy of the flow reading as this is subject to
calibration. A higher stability level indicates higher level of repeatability and
better flow-tracking.
Flow Record Tab
The Flow Record provides a record of flow over time. Each point of flow on
the graph represents a 1.2 second interval. However, when the trace button
has been pressed and a trace is being retrieved from the Flow Pulse this
slows down how frequently a point on the graph is plotted and the points
then represent a 2 second interval.
You can zoom in by clicking and holding the mouse then selecting the
region to zoom in on. Zoom out by right clicking on the chart and selecting
“Undo All Zoom”.
To clear the Flow Record chart, select Setup->Clear Flow Record Chart menu
while the chart is inactive.
