Fiber Optic Monitoring

One fiber equals thousands of sensors

With fiber optics, the fiber itself is the sensor. Laser pulses sent through a standard telecom fiber continuously measure temperature and vibrations with a high level of accuracy.

Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) are fully distributed systems that can measure temperature and vibrations several tens of kilometers of fiber at a time.

The back-scattered laser light provides temperature or vibration data. Fluves calculates parameters such as fluid flow or pipeline leakage on each and every meter along the entire fiber length.

Fiber optic sensing offers several advantages over electronic sensors: the ease of combining different sensors on one cable, the lack of electro-magnetic interference and a signal without any loss or drift.

Optical fiber can be installed while an asset is being built, or retrofitted in existing infrastructure. Up to 70 km of fiber can be monitored by a single system.

Theoretical Aspects of Fiber Optic Sensing

Critical equipment

Critical equipment, such as furnaces, underground pipelines, reactors, or tanks, can be difficult to reach.

Traditional point sensors cannot achieve complete coverage of such equipment. With fiber optic sensors, however, every meter of these critical assets can be monitored continuously. Faults are detected before they appear, avoiding downtime and extending the lifetime of your site.

The fiber optic cable is installed on or near the critical equipment. Fluves connects the cable to the client's IT infrastructure, and supplies software that transforms the measurements into actionable insights.

Operators are warned by mail, SMS or SCADA when faults are predicted or detected.

Pipeline monitoring

Our DALI technology uses fiber optic sensors to automatically pinpoint leaks and intrusions in pipelines.

The fiber optic sensing technology we use for DALI is Distributed Acoustic Sensing (DAS).

After a fiber optic cable is inserted in the pipeline, the DAS system records the leaking sounds along the fiber. A single DAS system can monitor up to 70 km of fiber.

When a leak is detected, we alarm the pipeline operator within minutes through e-mail, SMS or SCADA systems.
