The ILB24 constantly monitors the downstream pressure of the pipeline and can be configured with a high- and low pressure limit. For each limit a major and minor pressure threshold can be set and if those are reached a predetermined action is performed.

The rate of drop is used to determine if a pipeline rupture has occurred. If the pressure drops at a preset rate (measured in bars per minute), a major or minor alarm is triggered, and an automatic shutdown of the pipeline can be conducted.

The rate of rise indicates a sudden increase in pipeline pressure. If the preset major and minor thresholds are reached, a major or minor alarm is triggered, and an automatic shutdown of the pipeline can be conducted.

The differential pressure shows the difference between the upstream and downstream pressure in the pipeline on each side of the valve. A pressure transmitter is placed to monitor the pressure on each side, which calculates
the pressure difference. If the predetermined threshold of the differential pressure is reached, a minor or major alarm is triggered, and an automatic shutdown of the pipeline can be conducted.

Movement alarm detects if the valve has not reached full open or closed within a defined time.

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.
