China Passage Pig Signallers are used to determine whether a pig has passed or arrived. It is usually placed on the sending and receiving ends of the pig, as well as at key locations on the pipeline. And if you have any other questions, please contact our professionals to answer them for you.

Overview Pig Passage Indicator is a mechanically triggered explosion-proof digital display ball indicator. It is usually installed on the ball pipe. And it can detect whether the pig passes. The product has a built-in real-time clock. In this way, the exact date and time of the last pig passing and the total number of ball passes can be recorded.

EMT make Pig Signaller simpler and more effective: EMT’s range of intrusive pig signallers is detector instruments mounted on pig launchers and receiver stations to confirm the launch or arrival of a pig. They can also be mounted at any location on a pipeline and will detect the passage of all types of pipeline pigs. Our intrusive Pig Signaller uses a unique magnetic system to prevent fluid exchange blocked, therefore, it eliminates the risk of leakage from the action seal, also the trigger of the instrument is enhanced flexibility, reduces maintenance costs, and is easy to install to pipelines.

Removable Pig Signaller used in pipeline pigging operations are generally installed on the incoming and outgoing pipelines of long-distance pipelines. After long-term use, the ball indicator will have equipment corrosion and aging of the rubber seal ring of the movement. This will lead to different degrees of oil and gas leakage, indicator action failure, and other faults. The current solution is to shut down the pipeline. The operator will relieve and empty the oil and gas in the pipeline. And then repairing and replacing the indicator movement.
