Abstract

The present invention is directed to a method and apparatus for monitoring liquid flow using a generally elongate housing (12) having first and second ends (16, 18) having formed therein a liquid inlet and outlet, respectively, for permitting a liquid flow through the elongate housing, and wherein the elongate housing has a cross-sectional profile which varies along the length of the elongate housing so as to impart predetermined flow characteristics to a liquid flowing therethrough. A flow rate indicator float (40) is disposed within the elongate housing operative to be displaced therealong in accordance with a liquid flow rate therethrough and a flow rate indicator means associated with the flow rate indicator float, are used for providing a position-related indication of the rate of liquid flow through the elongate housing.
