
In order to avoid a thread joint gas leakage, use thread sealing
lubrication R-402 (TU 38.101.330-73) or a sealing tape FUM 0,1х20 (TU
6-05-1388-86).
4.4.3. Level gauge disassembly

Turn off the tool.

Close the gate valve of the technological tap.

Open an outlet valve of the tool and let the excessive pressure
out of the working body.

Screw out the level gauge and take it off the nipple. Drain the
working body off the condensate, clean a thread part and house the tool in
its bag.

Place the end cap on the nipple.
5. ARRANGEMENT AND OPERATION OF THE TOOL
5.1. General information
The
“SUDOS-mini 2”
level gauge is a compact electronic mono-unit
tool. It is a completely self-contained tool and provides all functional
abilities of a well level gauge. The tool is capable to display all basic
monitoring parameters and results immediately.
The level gauge provides level control for wells with low annular
pressure with the acoustic pulse generator GAI-01 .
The tool supports export of information to a computer. An applied
software DB "SIAM" included in the delivery set, makes it possible to
create and add computer data bases, to process and analyze measurement
results in more detail.
5.2. Arrangement, application and operation of components
5.2.1. SUDOS-mini 2 level gauge
The level gauge is intended to generate acoustic pulses in the
annulus, to receive and convert an acoustic response (an acoustic signal), as
well as to determine the fluid level and to monitor pressure at the well
head. The tool operates according to its internal program controlled with a
built-in microprocessor controller which synchronizes the operation of all
the components, processes the data transferred from primary transducers,
