Introduction

A pig indicator is a device that’s typically mounted on a pipeline. Installed directly onto the pipeline, pig indicator can detect the passage of various kinds of pipeline pigs, which are devices used for cleaning or inspecting pipelines. The pig indicator is equipped with an interactive flag that interfaces with the trigger mechanism.One of the key advantages of pig indicators is their easy installation process, facilitated by a flange connection. The flange, which can be customized into different sizes, ensures the pig indicator can be adapted to fit the requirements of an extensive range of pipelines. This makes the pig indicator a versatile tool for pipeline maintenance and inspection tasks.
