ILB24 product line

The ILB24 is designed to handle all the tasks an intelligent line breaker could be used for. It provides a straight forward solution to monitor and shutdown the pipeline in case of an emergency. The controller constantly monitors the pressure of the pipeline and will shut down the flow of the pipeline if abnormal pressure is detected.

The controller comes in various enclosure types that are suitable for all kinds of hazardous environments and have the appropriate area approvals for these environments

Pipeline monitoring capabilities

The ILB24 monitors the pressure in pipeline 24/7. The results can be read directly on the unit or from remote by using VCDC.

Major and minor alarms
When configuring the ILB24 a minor and a major pressure threshold are set. If the minor pressure threshold is reached an alarm is displayed on the ILB24 and a message can be sent to the control room. A minor alarm will not trigger any automatic action and it is up to the operator for any onwards actions.
If a major pressure limit is reached the ILB24 can be configured to do an automatic shutdown of the pipeline. It is also possible to only display a major alarm message and not do any automatic actions.

Sensors needed

Each pipeline monitoring feature requires specific sensors to be placed at various points in the valve system.

The list below shows the sensors needed at the upstream pipeline, downstream pipeline, and valve position.

Sensor needed

Downstream pressure

Upstream pressure

Valve position

Low- and High-pressure
