Cavernomer-profilomer well device

Determines the cross-sectional dimensions of the wellbore and its average diameter with two mutually perpendicular dimensions at the same time. The device uses a special device to remotely control the wings and perform calibration operations using a standard signal while the device is in the well. It connects to Weber-01 and Kedr 02 stations and operates with a 3-core geophysical cable up to 6,000 meters long.
