Graviflow is a French startup that manufactures water flowmeters with an innovative patented technology. 
 
Our water flowmeters are very precise, better than 98% exactitude, from small flows, on an effective range of 0.1% to 100% of the nominal flow, very easily to install on existing hydraulic structures without requiring significant work and are “plug & play”. 
Our flowmeters are made of robust 316L stainless steel, machined with great precision. 
Our flowmeters are made in standard diameters from DN100 to DN1200. 
The maintenance is reduced. GRAVIFLOW flowmeters can be controlled on site without disassembly by a metrological procedure validated by water agencies. 
We provide standard shims and gauges for in place metrological testing by the operator or an approved testing agency. 
 
Available functions :  
• alarms on thresholds, 
• sampling equipment control, 
• flow regulation (valve control), 
• data logger option, 
• low power option. 
 
Areas of use (typical) : 
• sewerage networks, 
• water springs, 
• industrial fluid networks, 
• sewage treatment plants, 
• combined sewer overflows, 
• pumping stations inflow and overflow. 
 
Decisive benefits :  
• insensitivity to flow regime, even changing flow regimes, 
• compact design, 
• no field adjustment required, 
• COFRAC connected hydraulic bench calibration certificate provided, 
• low cost of the measuring point. 

F-Reg solutions are designed to combat flooding and waste discharge in cities caused by overflowing sewage systems during heavy rainfall. As a result of new waterproofing and climate change, wastewater and rainwater collection networks are now often undersized in historic areas. As a result, they tend to saturate and overflow with effluent during rainfall, causing urban flooding and, above all, frequent pollution that degrades the biodiversity of our natural environments. Every year in Europe, flooding’s causes million worth damage (13 Billion €/year in Europe) and our cities are dealing with important risks of pollutions caused by these flooding’s.

The authorities are often trying to compensate these problems with large and expensive retention tanks. To counter these phenomena, F-Reg has patented a solution that turns our networks into regulating bodies by mobilizing water collection pipes for storage, thus smoothing the devastating peak flows generated by storms and preventing overflows. Today, F-Reg markets a range of solutions to meet the different needs of local authorities: stand-alone hydrodynamic valves, hydrodynamic regulating-controlled flow valves, tilting weirs, macro-waste traps and more.

The company is involved in projects from A to Z: from the study to analyze project needs (eligibility, sizing, location) through its engineering and design department, to custom 3D design, material manufacturing and finally installation of the solutions. The solutions created by F-Reg not only save local authorities money, but also help them make a commitment to the environment. In fact, the valves designed by F-Reg’s teams are much less expensive to install than rainwater retention basins and require no land. Installation is therefore much simpler, quicker, more eco-friendly, and more sustainable. F-reg solutions also improve the carbon footprint compared with the installation of a retention basin.

SIDE Industrie is a French family company specialized for over 30 years in solutions for the pumping of “difficult fluids”. Based on practical expertise in the field, the development of its product range is the result of 30 years of research, and from listening to the daily concerns of its 2500 users worldwide, enabling them today to offer a revolutionary alternative to wastewater lift stations that saves time and money: called DIP (Direct In-line Pump) systems in France and OverWatch (OW) for international markets . They count now over 2500 references (new pumping stations and renovation of existing installations) all over the world.

By lifting gravity effluent directly at the point of entry, without water loading nor a wet well, the OverWatch Direct In-Line Pump overcomes the drawbacks of retained volumes of effluent such as: dangerous gases (H2S), smells, sand and grease accumulation, equipment corrosion, structural erosion, clogged floaters; and offers access safety.
Derived from the OverWatch Direct In-line Pump we also offer the products SIDINOX-PLS (Packaged Lift Stations), Single pumps (DomoDIP, DIPM and PM ) thus covering all sewage, storm water and industrial water activities.

The OverWatch Direct In-Line Pump’s stainless steel body is designed to withstand the effects of corrosion form harsh materials and solutions. All those assets (contained effluent, no odor, no wet well, no blockage, smart sensing, reduced maintenance, …) allows the OverWatch Direct In-line Pump to be the perfect solution for Industrial, Municipal and Commercial applications.
The smart-sensing system adjusts in real-time to manage flow and avoid clogs, guaranteeing continuous operation. Thanks to its patented DIPCut impeller all rags and fibers are shredded to clear any blockage.

The BOOSTER : our latest innovation ! The applications of this new circulator are mainly in the case of collectors and pipes lacking slope, or pipes undergoing point loads, or insufficient pipes.
It makes it possible to increase the flow rate of a gravity pipe from DN 200 to DN 1200 (other dimensions on request). It also allows the forcing of existing pipes within the framework of the fight against flooding.

All those products are sold and manufactured by SIDE Industrie in partnership with Industrial Flow Solutions.

Hasler-Group has been offering quality equipment solutions for environmental applications for decades.
Our industrial agitators (mixers) have proven their reliability in municipal water treatment for coagulation/flocculation/settling/MBBR… The same is true for industrial wastewater treatment with specific coatings, materials, specific designs, Computational Fluids Dynamics (CFD) if necessary…

Our horizontal vacuum belt filters are also known the world over for their cost-effectiveness and strong reliability when it comes to gypsum dewatering in FGD (Flue-Gas Desulfurization) plants, either for utility plants (coal-fired power plants) or non-utility plants (industrial incineration/power plants).
With loyal and prestigious customers on every continent, as well as agents and partners supported by our 2 plants and 6 offices around the world, there certainly is a Hasler contact near you.
