Monitor every meter, every minute

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, vibrations and strain with a high level of accuracy.

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

How does Fiber Optic Sensing work

The back-scattered laser light provides temperature, vibration or strain 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, plus it's ATEX-proof.

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

Fiber optic sensing for corrosion under insulation

Monitoring CUI (Corrosion Under Insulation) with fiber optic sensing has been a groundbreaking innovation for maintenance and asset managers in the chemical industry. > Read an interview with BASF here. <

Our newest technology CUI-CONTROL can:

  • Detect corrosion at the earliest stages, even before it happens.
  • Accurately pinpoint where exactly (one meter accuracy) the corrosion
    is happening.
  • The metrics can differentiate between spots with a high risk for corrosion and spots in the early stages of risk.
  • CUI-CONTROL runs autonomously. Your manual inspection teams can focus on something else.
  • You can follow the metrics via a digital dashboard on your computer and you will be notified when needed.


More info can be found on the CUI-CONTROL website.

Fiber optic sensing to monitor leaks and intrusion in underground pipelines

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.

More info on DALI can be found on our DALI website.

Fiber optic sensing to monitor furnaces, tanks and reactors

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

Traditional point sensors cannot achieve complete coverage of such equipment. With fiber optic sensing, 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. We connect the fiber optic cable to your IT infrastructure, and we supply software that transforms the measurements into actionable insights.

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

  • Monitor hotspots
  • Monitor uneven heat distribution
  • Monitor wear & tear of insulation
  • Monitor process temperature
  • Monitor structure health

Internet Of Things (Iot)

Internet of Things (IoT) is technology that enables to connect objects over a wireless network at an extremely low cost. IoT devices typically contain sensors, mini-processors and modems. The wireless network can be GPRS, LoRa, NB-IoT, LTE-M. Data is aggregated onto a web portal provided by Fluves.

Internet of Water

Fluves provides custom IoT-sensor networks for water systems. Alerts can be generated leading to improved and cost-saving water management.

We measure parameters such as water level, flow velocity and water quality. Our sensor platforms can be installed remotely, in sewers or rivers, powered by solar and/or batteries.

IoT water level

Water level

Fluves provides the world's simplest and cheapest water level sensors. Water levels are measured through ultrasonic signals. A sensor, a datalogger and a modem are integrated in one compact box that can be installed in open water or closed environments such as tanks, cisterns and sewers.

Water flow

Water velocity is measured through radar signals powered by Geolux. Flow discharge can be measured by measuring both water velocity and water height. No equipment maintenance is needed because our systems measure the water velocity contactlessly.

IoT water velocity

Water quality

Our IoT water quality sensor is a fully autonomous, solar-powered unit that measures electrical conductivity and temperature. The electrical conductivity measurements reveal the purity and the salinity of the water.
