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.
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.

Critical equipment, such as underground pipelines, reactors, ovens 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.

Fiber optic sensors offer highly detailed insights in the erosion of polluted sediment in water bodies. The very same fiber can detect seepage flow through the cap along every point of the fiber optic cable.
After installing the fiber optic cable in the body of water, Fluves uses the measured temperature to calculate the thickness of the sediment layer along the cable.
The sediment level and seepage of every square meter of many hectares can thus be continuously monitored in a cost-effective way. Applications are monitoring of cap thickness and seepage through a cap or evaluation of EMNR/MNR sites and mine-tailing ponds.

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.
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.
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 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.
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.
