7. MEASURING
ATTENTION! While performing work on a well, strictly follow the
requirements and provisions of the Safe operating Instruction (Section
4).
7.1. Fluid level monitoring
Press the LEVEL key and keep it
pressed for about one second until the l
symbol appears on the display. It means
that the tool is ready for level
measuring. During this one-second
pause the level gauge measures a noise
level in the well and automatically
determines
a necessary operation
threshold.
The digit place in which the
I
symbol is displayed depends on the
noise level: the higher the noise, the
more right the
I
symbol appears.
During a pause, the indicator displays the inscription "NOISE
AMPLITUDE ANALYSIS". After two symbols (
I
) appear on the indicator,
generate an acoustic pulse by briefly pressing the handle of the level gauge
manual valve to the stop.
7.1.1. Echogram recording and level determination
The next 20 seconds after an acoustic transient pulse has been
generated the tool detects and records acoustic data from the well. Acoustic
data detection can be observed on the display showing the signal peak level
in 50 gradations (the more right the symbol moves the higher the noise
level is).
After 20 seconds the Level determination symbol appears on the
display. This symbol shows that the detection and recording of acoustic
transient data have been finished and the tool is in mode of echo-gram
analysis and level calculation.
