Abstract:
A water meter to measure the flow of water from a water source, said water meter comprising:a hollow body having an inlet port to be coupled to the water source to receive a supply of water therefrom and an outlet port through which the supply of water is delivered to a user; a turbine located within said hollow body and having an entrance passage formed therein and aligned with said inlet port in order to receive the supply of water from the source by way of said inlet port, said turbine including a rotor responsive to the supply of water received through said inlet port so as to provide an indication of the amount of water flowing through said hollow body between said inlet and outlet ports thereof; adjustable flow control means to control the rate at which the supply of water is received by said rotor through the entrance passage in said turbine by way of said inlet port; and a variable water inlet orifice formed through said turbine and aligned with said rotor, and a flow regulator adapted to be displaced relative to said variable water inlet orifice to change the size of said variable water inlet orifice and thereby control the rate at which the supply of water is received by said rotor through said inlet orifice by way of said inlet port.
