Our flowmeters have been in constant evolution since 1974, until becoming convenient for a wide
range of applications. They get more precise, practically insensible to electrical interferences or airlocks. Typically installed where the relation of height and speed is out of place, these flowmeters allow up to 6 speed integrations (6 chords). Thanks to the microprocessors era, they give lots of information to the user. The softwares permit instantaneous measurements and logger (1Mo) conversion into data files compatible with modern communication systems (RTC,GSM..).
Our ultrasonic flowmeters have several advantages such as :
 | their capacity to measure very slow (<1cm/s) or fast speeds |
| a great dynamic of measurement |
| the bidirectional measurement |
| no pressure drop |
| the accuracy of measurement in difficult hydraulic applications in downstream or upstream slopes (ascent of rivers or expanse of water, dam, lock...). |
so they are very convenient in applications such as :
• Sewage treatment :
| open channels measurements from 500mm up to several meters width
| | the discharges in the environment (factory, storm spillway...)
| | inflow-discharge from sewage works
| | process regulations in factories
| | network measurements
| | All measurements in gravitory flows diameters of 500 mm up to several meters. |
• The distribution channels and the environment for :
| all works below 1 meter and up to 300m width |
| irrigation |
| annoncements of rise in the water level |
| flow measurements for rivers (no disruption of the circulation) |
| the rivers basins monitoring |
Our main customers in France are the DIREN (regional evironment services), the DDE, DDA (agriculture and equipement services), the institutions in charge of the river basin monitoring, the canal of Provence, the canal of Carpentras...
• Our provisions of a service :
Usea proposes the complete management of your projects. Our experience is entirely at your disposal to take part in :
|
the equipment definition, the place of the measurement points |
|
the working out of probes supports |
The works due to the installation of these flowmeters are often expensive and delicate. Usea is now able to :
| select the participants (civil engineering, river works...) |
| oversee the building sites |
| ensure their receipt |
| take part in the adjustment and standardization of your flowmeters. |
The repatriation of measurements in real or delayed time is now an essential element of these stations. The experience of Usea is at your disposal for selecting the supports of data transmission and softwares adapted to your needs.
