An apparatus for measuring the rates of flow of fluid through a line, which is characterized by a fluid driven turbine whose axis may be pivotably varied throughout an arc from being parallel to the direction of fluid flow to a position perpendicular to the direction of fluid flow. By varying the angle at which the fluid flow impinges on the turbine wheel the "K factor", that is the rate of turbine rotation per unit of fluid flow can be adjusted so as to adapt the flowmeter to differing fluids (such as, steam, air and other gaseous fluids, and, both low and high density liquids). Also, by varying the angle at which the fluid flow impinges on the turbine wheel the rate of turbine rotation per unit of fluid flow can be adjusted to adapt the flowmeter to a very wide range of flow rates (high rangeability).
