will immediately switch to the echogram recording mode. Therefore, after
the appearance of the inscription "RECORDING ECHOGRAM",
immediately generate an acoustic impulse by briefly pressing the handle of
the level gauge manual valve to the stop. 20 seconds after the beginning of
the recording of the echogram, the inscription "FILTERING" will appear,
which will be displayed for 9 seconds. In this mode, the level transmitter
generates a conventional echogram for level determination from a
broadband echogram. Next, the inscription " LEVEL DETERMINATION"
will appear. And after 1..2 seconds the result of the level determination will
appear.
7.2. Automatic recording of gas pressure in the wellhead annulus
Install the level gauge on the nipple of the technological tap (see
Section 4.4.2).
After having placed the tool in a position comfortable for access to
the keys and observation of the display, turn it on and set (if they have not
been set beforehand) a number of a well and a well cluster, an automatic
gas pressure recording test type
(KVD mode) (Mode 3) and an interval of
the tool's operation. Press the LEVEL key. The display will show:
СТАРТ КВД
The level gauge starts its operation in 5 seconds and it will
automatically come on in a set time period, operate during 0.2 sec. (it
measures the pressure and records the measurement result in the storage),
automatically go off, and so on.
It is recommended to select such a period of measurements so that
within a total operation period the tool makes not more than 12064
measurements.
