The equipment was development by AO NPP VNIIGIS in cooperation with OOO NPP INGEO and OOO NPP INGEO-Service
Designed to measure the diameter of ore, coal and hydrogeological wells.
The downhole tool is to be run with log recorders “VULCAN V3, KEDR-02 or similar.
Operates with one-core or three-core logging cable.
FEATURES AND ADVANTAGES
- the ability to remotely control the opening and closing of the 3-lever measuring system using a small electrical motor with a gearbox;
- small diameter of the tool without filling with transformer oil;
- original hydrostatic pressure compensation system
