The Intrusive Pig Signaler

Detecting cleaning pigs, accurately and reliably

At Apache, we know that knowledge is power. That’s why we want to make certain that when a customer is pigging a pipeline, they will always know when the pig has passed a critical point in the pipeline.

To achieve that, we designed the pigPRO™ Series, a patented line of intrusive pig passage indicators that reliably detect the precise location of a cleaning pig as it travels within the pipeline network.

How does it work?

The pigPRO indicator is permanently installed on pig launchers and receivers, or very close to a pump station. By doing so, operators are notified the instant that the pig has left the launcher or arrived in the receiver.

The system is fitted with a plunger that is then inserted into the pipe, physically penetrating the pipe bore. When a pipeline cleaning pig passes, it actuates the plunger, which activates either a visual or electrical indicator, or both. The instant that the indicator is displayed, the pipeline cleaner’s precise location is revealed.


The Base Model 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 precise 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, signaling the pig’s location.

Easily installed without disrupting production. Every model in the pigPRO series is easily installed, even while the pipeline is on-stream. So preparing for critical pipeline cleaning doesn’t disrupt critical production.

Fewer moving parts ease installation & reduce risk. Most pig indicators feature trigger mechanisms with many moving parts that make it more difficult to align during installation. As a result they are frequently damaged. With the pigPRO’s hemispherical design, these issues are completely eliminated, saving time and money.

To ensure that the indicator is properly adjusted for the individual pipeline, hemispherical plunger sensitivity adjustment and hemispherical plunger penetration adjustment are standard features.

Bi-directional activation. Every pigPRO indicator is bi-directional, so it is triggered by a pig traveling in either direction. Although a pig is rarely required to travel in the opposite direction of the flow in a pipeline while it is on-stream, this capability can be useful when servicing offline pipelines.

Debris or no debris, pigPRO performs. When it comes to indicating pig passage, wax or debris in the line, most pig indicators simply can’t operate. That’s not the case with the pigPRO, which operates reliably, regardless of wax. It’s specially designed to prevent debris from obstructing its operational mechanisms, so a passing pig is always indicated.

Universal, adaptable. Our ability to retrofit to most mounts makes the Apache pigPRO completely versatile.

The Model 55 is an electrical indicator with manual and automatic reset.
With its optional manual and automatic reset capabilities, the Model 55 is a highly sought after member of Apache’s pigPRO™ Series, a patented line of intrusive pig passage indicators that reliably detect the precise 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, signaling the pig’s location.
