ABOUT US :<\/h2><\/div>\n\n\n\n
<\/div>\n\n\n\n

Graviflow is a French startup that manufactures water flowmeters with an innovative patented technology.<\/p>\n\n\n\n

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 \u201cplug & play\u201d.<\/p>\n\n\n\n

Our flowmeters are made of robust 316L stainless steel, machined with great precision.<\/p>\n\n\n\n

Our flowmeters are made in standard diameters from DN100 to DN1200.<\/p>\n\n\n\n

The maintenance is reduced. GRAVIFLOW flowmeters can be controlled on site without disassembly by a metrological procedure validated by water agencies.<\/p>\n\n\n\n

We provide standard shims and gauges for in place metrological testing by the operator or an approved testing agency.<\/p>\n\n\n\n

              GRAVIFLOW, the solution in the case of gravity flow<\/strong><\/p>\n\n\n\n

              The GRAVIFLOW process allows our flow meters to perform a fair and reliable measurement in most cases of gravity flow, and particularly in cases where other devices on the market are not satisfactory.<\/p>\n\n\n\n

              Best solution<\/strong><\/p>\n\n\n\n

              When flow regimes are variable or turbulent our flow meter is the best solution.<\/p>\n\n\n\n
