5.2.2. Ball-type Nozzle
The ball-type nozzle (the rubber sphere) is
designed for generating an acoustic impulse when
there is no excessive gas pressure in the annular
space of the well. The ball-type nozzle is made up
of the rubber sphere and the coupling. The ball-
type nozzle is actuated by a violent blow of the
hand on the sphere. An acoustic impulse, sufficient
for positive control of the fluid level in wells up to 600…800 m, is formed.
After the acoustic impulse is generated, the rubber sphere should be kept in
the position which it took immediately after the blow until the value of the
measured level pops up on the screen. The ball-type nozzle is screwed on
the well sounder instead of the retrievable manual valve by using the
reduction sleeve supplied with the device.
5.2.3 Power supply with USB connector
The power supply with USB connector is designed to power the
charger integrated in the device. The power supply unit is connected to the
220 V/50 Hz mains, the device is connected to the USB slot of the power
supply unit via a USB interface cable.
The power supply unit ensures the normal parameters of the charging
process at mains voltages of 190 to 240V, with a DC voltage of 5V at a
load current of at least 500 mA at its output.
5.2.4 А car power supply unit with USB slot
А car power supply unit is untended for charging the level gauge
with а fixed voltage of 12V from the car power supply in the field
environment.
The car power supply unit is connected to the on-board power
supply of the vehicle, the appliance is connected to the USB slot of the
power supply via the USB interface cable.
ATTENTION! The battery cell's temperature should bе in the
range of + 5

С up to +30

С.
Note - A car power supply with USB connector is available as an
option.
5.2.5 Interface USB cable USB
The interface USB cable is intended to connect the level gauge to a
computer and to transfer data from the tool to a computer database, and
