<p>This invention relates to turbine flow meters for the detection and measurement of flows of liquids. The invention provides a turbine liquid flow meter with a rotor including a plurality of helical vanes, the rotor being adapted such upon viewing the rotor in an axial direction the leading edge of a vane aligns with, or overlaps, the trailing edge of an adjacent vane. The invention also provides a turbine liquid flow meter with a rotor which is rotatably mounted by means of an axle extending from each end of the rotor and supported by a journal bearing, wherein fluid communication is provided between the journal bearing and the axle of the rotor.</p> |
