Applications of Intrusive Type Pig Signaller
In the oil and gas industry, operators use intrusive type pig signallers to monitor pigging operations. First, these devices detect the passage of pigs through the pipeline. This ensures accurate tracking and timing of pigging activities. Additionally, they help identify any delays or issues during pigging. With this information, operators can promptly address problems and maintain efficient pipeline operations.
Similarly, in the water treatment industry, intrusive type pig signallers play a crucial role. They provide real-time data on pig movement through water pipelines. This helps operators ensure thorough cleaning and maintenance. Furthermore, these signallers enhance safety by confirming pig passage before opening pipeline sections. Their reliable performance supports effective pipeline management and reduces downtime.
