Smarter Pipeline Management

(in lingua inglese)

There are various international standards and legal regulations in place for pipeline integrity. To minimize possible damages one particularly important stipulation is the use of a leak detection system (LDS).
With HIMA, you have two options. The FlexSILon PMC Hybrid solution, the world’s first LDS integrated straight into an emergency shutdown hardware system or the traditional FlexSILon PMC solution, which includes the PC-based LDS FLOWorX.

 External Leak detection systems are usually more costly
 Internal leak detection systems typically use the existing pipeline instrumentation.
 Internal leak detection systems offer the flexibility of connecting to the instrumentation via the SCADA system.  Internal leak detection systems send alarms back thru the SCADA system.
 Internal leak detection systems are fast to detect leaks ' depends on type of a leak, the detection time can be in seconds or minutes HIMA Paul Hildebrandt GmbH 2017 16 Internal vs External for
