Automated Control of the Velocity of In-Tube Diagnostic Tools for Main Gas Pipelines: II. Electronic Equipment of a Bypass Device

摘要

The design and operation of electronic in-tube nondestructive-testing equipment containing a bypass device are described. The electronic equipment designed for the bypass device is built in the general system of onboard electronic equipment and performs automatic control of the preset velocity of a flaw detector or other diagnostic pigs moving through a pipeline.
