  4. Easy Installation: The flange connection design simplifies the installation process, ensuring quick integration into existing pipeline infrastructure.
  5. Compatibility: The pig signaller is compatible with different pig types, including scrapers and spheres, without requiring additional magnet inserts in the pigs.

Working Principle

The pig signaller with flange connection operates on a mechanical contact explosion-proof indicator system. When a pig passes through the trigger point, a striker mounted on the extension sleeve moves, transmitting the action to the instrument button. This triggers the display instrument, which records the passage of the pig and displays relevant parameters. The real-time time display and recording system ensure accurate tracking of pig movement and timing.

Maintenance

To maintain the optimal performance of the pig signaller with a flange connection, it is essential to follow proper maintenance practices. While the part above the flange can be disassembled under pressure, it is recommended not to do so unless necessary. The O-ring for sealing below the flange is a consumable part and may require replacement over time.

The working principle of the pig indicator involves a striker with bidirectional triggering mounted on the end of the extension sleeve. This striker is positioned near the pipe wall through a connecting pipe, typically with a DN50 probe. When a pig passes through the pipeline, the movement of the striker is transmitted to the instrument button via a connecting rod within a sealed bushing. As a result, the instrument is triggered to work and display the necessary information.

The instrument includes a main body and a display instrument, connected by knurled nuts. It features indicator lights for Hit impact and test/reset functions. The upper row of the display shows the number of pig passes and accumulated timing value, while the lower row displays the current time. The instrument has a built-in real-time time display and recording system, allowing for parameter recording and easy monitoring of pig passage.

This pig indicator with a flange connection is suitable for use in explosive gas and flammable medium environments. It conforms to explosion-proof standards with a dⅡBT4/IP55 rating, ensuring safety and reliability in such settings. The indicator can be customized with different penetration lengths, catering to specific pipeline requirements.

Overall, the pig indicator with flange connection provides a practical and efficient solution for monitoring pig passage in pipelines, ensuring the smooth operation of pipeline processes while maintaining safety and accuracy in various industrial applications.
