Abstract

PURPOSE: To obtain a high sensitivity of water meter by forming the inside diameter of a straightening vane case smaller than the outermost diameter of a turbine.
CONSTITUTION: The water meter has its inside diameter D2' of a turbine case 9' and outermost diameter d' of a turbine 2' enclosed on the turbine case 9' formed smaller than inside diameter D1' of a stragihtening vane case 8' to d'>D1'. A meter high in sensitivity as compared with that of a conventional shape is thus obtainable.
