In 1 or 2 sec. after the beginning of calculations, a level measurement
result is displayed. E.g.:
The example shows the fluid level has been measured at the depth of
1030 m., and 2 reflections of an acoustic transient signal from the fluid
level have been recorded. Measure time is 16 hours 53 minutes.
For each calculation the calculated value of the fluid level, the
number of reflections, research parameters and a graph are automatically
recorded into the tool’s storage for symbol reports and into the storage for
echo-grams combined with symbol reports. Hence, symbol reports are
recorded into the echograms storage and are duplicated in the storage for
symbol reports.
To make the monitoring results more reliable, it is highly
recommended to reconduct the level measurement.
If the measurement results significantly differ from each other, it
testifies that the tool cannot determine the fluid level automatically. This
can be caused by different reasons (some of them are considered in
Supplement 1). In this and as well as in other doubtful and necessary cases,
it is recommended to determine the fluid level according to an acoustic
transient signal graph. One can get an acoustic transient signal graph when
transferring measurement data to one of the tools, i.e. a personal computer,
a visual monitoring unit (see Supplement 7).
7.1.2. Recording a wideband echogram (for a wideband level gauge)
To record wideband echograms from a manual valve, press the
LEVEL button. The “I” symbol will appear on the indicator. The digit of
the indicator in which the symbol appears depends on the noise level: the
higher the noise level, the more right the symbol. The level gauge will
measure the noise amplitude in the well for 2 seconds and after 2 seconds it
