The base model Series 57 is a visual flag indicator with manual reset.
It is a popular member of Apache’s pigPRO Series, a patented line of intrusive pig passage indicators that reliably detect the previse location of a cleaning pig as it travels within the pipeline network. When a cleaning pig passes the system’s intruding plunger, it activates the plunger and triggers a visual flag indicator, signalling the pig’s location.
