Well sounders «DU-1»
Arrangement of the elements inside the threaded coupling cavity is
given in the figure of the level indicator:
1 - acoustic sensor;
2 - pressure sensor;
3 - fitting.
Cleaning is done using pure gasoline, a brush and a cleaning rag. It
is allowed to pour a small amount (50…100ml) of gasoline inside the
threaded coupling cavity while cleaning. However, do not immerge the
well sounder housing in the cleaning liquid, and do not let its ingress in the
connector. When cleaning a very dirty thread, application of metal tools
(an awl, a screwdriver, etc.) is allowed, but do not apply an excessive force
not to damage the thread.
It is strictly forbidden to use a metal tool for cleaning the acoustic
and pressure sensors. Moreover, be careful not to apply much force during
cleaning. Acoustic sensor housing is covered with a protective varnish, do
not damage it! It is forbidden to insert foreign objects in the pressure
sensor hole!
Wipe the surfaces with a rag after washing. Cleaning should result
in a metallic lustre on the coupling surfaces, connecting thread, acoustic
sensor, and clean holes of pressure sensor and fitting.
