摘要： A valve incorporates a device causing turbulents in the water stream just before passing over the turbine fins of the flow sensor. The device actually increases the Reynolds number or turbulence of the water stream increasing the contact of the water on the turbine. This causes the turbine to rotate more efficiently for the given flow volume passing over the flow measuring device. The improved efficiency results in better accuracy and performance over the entire flow range. In one embodiment the turbulent device forces the flow stream to rotate counter clockwise and hit the turbine fins causing higher force which makes the turbine turn more efficiently. The turbine is designed such that the major portion of the fin surface area is perpendicular to the turbulent flow stream. This opposed direction causes more force to be placed on the turbine fin by the water stream.
