METHOD FOR INDICATION OF LOCAL CORROSION LEVEL IN PIPELINES OF OIL GATHERING SYSTEMS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC G01N17/00 

FIELD: oil pipelines.

SUBSTANCE: invention relates to the field of ensuring trouble-free operation of field oil pipelines and can be used to evaluate the parameters of corrosion processes in them. The effect is achieved by the fact that a multichannel corrosion sensor is proposed that implements the electrical resistance method, including a reference current source, differential amplifiers, a processor capable of transmitting data to a computer network, a multichannel analog-to-digital converter, low-pass filters, switch blocks, a source bias voltage, characterized in that the reference part of the measuring probe is either connected to the free inputs of the switch block of each measuring channel, or is distributed so that each share of the reference part is located on the corresponding part of the surface of the measuring probe, and is connected to the free inputs of the switch block of the corresponding measuring channel, while the sensitive part of the measuring probe is immersed in a layer of bottom mineralized water.

EFFECT: providing operational multi-channel monitoring of the corrosion rate in the bottom mineralized water of pipelines of oil gathering systems.
