• Raw water => samples
• Drinking water => elaboration and distribution
• Waste water =>discharges

Our experience : more than 7500 installations in the
world.
| |
Our solutions are numerous with intrusive or external
probes, single or multichords spools, flowmeters and meters of an accuracy up
to 0.25%, a flexible budget...
We study your solution which depends on :
| |
- your need of accuracy,
- the reality of your installation conditions,
- the condition and kind of pipe,
- your budget
|
Our service may integrate advice for the installation,
the installation and optimization of the calibration on site, and the servicing
and guarantee of the metrology keeping. A modern ultrasonic flowmeter has no
problem of drift.
Our applications : if the modern tendancy gives
external probes more than their due as they have made progress, we must not
disown intrusive probes, guarantee of the signal keeping and above all
necessary to the counting of great accuracy in multichord technology.
|
- Our intrusive probes are installed in many important towns, in factories or
drinking water networks, on diameters from 500 to 3500 mm : CGE, Vivendi,
Sedif, Lyonnaise des eaux, Sagep-Paris...but also Bangkok, Bombay, Bogota,
Santiago of Chile... The installation and servicing have never required any
break in the operation.
- The most efficient and accurate countings (0.25%) have been obtained by the
installation of multichords system (4 chords in according to Gauss-Jacobi
modelling) in the SEDIF/CGE factories exit. A measurement by 6 chords has been
realized with the participation of the SAGEP on one of the main pipes for Paris
(Diameter : 2500mm).
|
- Some networks are made of pipes with cement coating, indeed in abestos
cement. The appropriateness of external probes permits simple and reliable
installations.
- Our installations also concern the treatment process, the regulation of
chemical products and of the postchloration, and the supervision of the washing
flow of the sand filters, active carbon or of type biostyr.
- The waste water are not forgotten even if they are often collected in
gravitory network (see our chapter on open channel applications). There are the
pumping stations in network or in inflow from water treatment plant.
- In a general way, with the agreement of the local authorities (water
agencies) our instruments are accepted for the measurement of pumping into
ground water table or river but also for the discharges.
