Wireless leak detection offers continuous monitoring and significant savings

In this case history, a new leak detection project saves around 60% compared to a conventional wired approach.

By Bob Karschnia, Emerson Process Management

Leak detection at large chemical sites can be both difficult and expensive. At one Belgian plant, operators were making twice-daily inspection rounds using portable leak detectors — but new and stricter government regulations required continuous monitoring instead. So, plant management decided to implement an online leak-detection system.

In 2013, after research on suppliers and technology, the plant installed a system that uses hydrocarbon fast-fuel sensors and sensor cables, and wireless discrete transmitters. An IEC-standard WirelessHART field network communicates leakage data from the remote transmitters to the plant control system.
