F7001 turbine flow meters (hereinafter referred to as turbines) are used for the precise measurement of instantaneous flow of low-viscosity fluids rates and flow quantities such as; tap and demineralised water, fuels, liquefied gases, Light fuel oil, solvents, Pharmaceutical fluids, etc. Turbine Flowmeters measure volumetric flow, where flow passing through the tube is measured by the mean velocity of the streaming fluid. Flow rectifiers ensure a laminar flow in the axial direction of the wheel. A light-weight turbine wheel carried concentrically in the tube body is rotated by the fluid. The RPM of the turbine wheel is directly proportional to the mean flow velocity within the tube diameter and corresponds to the volume flow over a wide range.
