Real-time observations & alarming

The Regional Government of Brussels Capital through its Water Division, decided to install a wide network of flow monitoring stations for data collection, real-time observations & alarming.
Real-time observations & alarming


The main activity of Flow-Tronic S.A. , founded in 1989, is based on water measurements. Velocity, level and flow are measured as well in waste water (open channels, rivers, etc…) as in potable and clear water (distribution water, cooling water, etc…). Dates are displayed locally, logged or transmitted by wire, radio, GSM or GPRS. 

Following customer’s specifications and requests, and in front of sites configuration, we are in a position to propose different measuring techniques like electromagnetic or ultrasonic sensors for velocity ; radar, ultrasonic or pressure sensors for liquid levels, and combinations of electromagnetic, radar or ultrasonic sensors for flow determination. We propose a unique non-contact flowmeter combining a level measurement with an ultrasonic sensor and a velocity measurement with a radar. A surcharge sensor can be added and in this case measurements are uninterrupted and there is lost of dates if the sensor is submerged. 

End of 2001, we signed with the Ministry Brussels Capital Region – Water Division a contract for the study, delivery, installation and maintenance of a net of 90 stations on the whole territory of Brussels. Actually about 30 stations are installed and dates are available on Ministry’s computers and located on a website. This site will soon be public for the main measurements and detailed information will only be accessible with a password for concerned professional people. 

During 2002 and 2003, we delivered and installed different nets of measuring stations in South Tyrol (North of Italy). The waste water plants requested from the municipalities a correct count of the water quantities sent to the treatment plants. The difficulty to install perfect working material in this mountainous region was a reason of the elimination of numerous tenderers. We sold there about 40 stations, with a quantity of 17 only in Merano. 

In 2004 and 2005, the Andalusian Municipality of Cordoba in Spain ordered through our Spanish representative about 25 stations, combining precipitation and flow measurements. Dates of rain, measured with our rain gauge, and flow, determined with electromagnetic but also with non-contact (ultrasonic / radar) flowmeters, are collected by our logging stations and transmitted to a municipal central control post by GSM.

The Regional Government of Brussels Capital through its Water Division, decided to install a net on its territory to collect a maximum of dates about water. It concerns rivers, creeks, sluices (on the canal crossing through the town), waste water pipes and collectors, storm water reservoirs and also pumpstations. 

Originally about 80 stations are foreseen for water measurements and 10 (or more) concern rainfall. Since the project has been started, numerous other sites have been added to the net. All measured values are logged inside each station ; the central system calls all the stations every 15 minutes and the dates are transmitted by GPRS. Afterwards they are available under schematic and graphical forms. Dates are put on the website of the Ministry for public consultancy ; more detailed information are hold only for professional consultancy on base of passwords. 

This very accurate and professional net has been ordered on base of a public tender won by Flowtronic end of 2001. Major tenderers proposed either very sophisticated or too simple solutions, while Flowtronic introduced an excellent technical proposal combined to an interesting pricing. 

This tool gives to the Municipality of Brussels a view on water flows on its territory. It allows the Water Division to survey the charge or surcharge of the waste water collectors net. It informs the concerned town authorities about the situation in the storm water reservoirs with indication of entering and outgoing water volumes as well as inside water levels. It permits to take care to eventual inundations in the district where this happens regularly. 

We include here below some pictures of different kinds of measurements and installations, mainly on the river Senne, on the canal (sluice), on some creeks (an incredible number of creeks flows on Brussels territory), on main waste water pipes and collectors, in a pumpstation, etc…
