Well sounders «DU-1»
3. BASIC SPECIFICATIONS
2.1 The device is designed for operation at the wellhead in oil and
gas fields and provides:
2.1.1 Fluid level measurement in annular space in the range of (20 –
3000) m, excess pressure measurement in the range of (0 – 100) kgf/sm
2
.
2.1.2 Measured data record and saving in a non-volatile storage
device.

2.1.3 The well sounder supports control and transfer of measurement
results to the terminal by means of Bluetooth radio channel (or Zig-
Bee on demand) at a range of at least 35 meters.
2.2 The device maintains its operability at ambient temperatures
from minus 40 C to + 50 C.
2.3 The device operates autonomously and is powered by a special
internal battery type EEMB LP103450LC-PCM-LD with 3.6 V or 3.7 V
voltage. The minimum operating voltage of the battery which does not lead
to a loss of performance of the device is 2.7 V.
2.4 The basic specifications are given in Table 1.
