How does a pig detector work?

A pig detector, also known as a pig detector, is a device used to detect the presence of a pig or pipeline inspection instrument in pipelines. A pig is a device inserted into a pipeline for cleaning, inspection, or maintenance. The following is a typical working mode of a pig detector:

When the pig is fed into the pipeline, it generates a series of pressure waves.

The pig detector is located downstream of the launch point to detect these pressure waves.

Then, the detector sends a signal to the control room or operator indicating that the pig has passed through the section of pipeline.

This information can be used to track the position of the pig in the pipeline and ensure that the pig passes through the pipeline as expected.

There are several types of pig detectors, including magnetic and acoustic detectors. Magnetic detectors work by detecting the magnetic field of the pig, while acoustic detectors work by detecting the sound waves generated by the pig. Both types of detectors are commonly used in the oil and gas industries to ensure the safe and efficient operation of pipelines.
