A single jet flowmeter with improved driving torque and sensitivity

A single jet flowmeter with improved driving torque and sensitivity

Single-jet fluid flowmeter that has a volume measurement error within metrological parameters in the range of 4 l/h and 5,000 l/h, is stable against hydraulic accidents upstream of the flowmeter, calcareous deposits, and allows tolerances that do not affect the metrological parameters. This flowmete...

description Single-jet fluid flowmeter that has a volume measurement error within metrological parameters in the range of 4 l/h and 5,000 l/h, is stable against hydraulic accidents upstream of the flowmeter, calcareous deposits, and allows tolerances that do not affect the metrological parameters. This flowmeter comprises a turbine, two nozzles and a measuring chamber. At least one of the nozzles forms an angle with the original direction of fluid flow of between 10° and 20°. The measuring chamber comprises a set of four upper ribs and six lower ribs, radially arranged and spaced at regular intervals. The ratio between the height at which the upper ribs project from the chamber varies between 1.5 and 1.7 times that of the lower ribs. Together with the abovementioned flowmeter, a measurement process is provided that incorporates this flowmeter onto an inlet duct and an outlet duct wherethrough the fluid is made to flow, and incorporates a counting element onto the flowmeter.
