  • Patent number: 5372048
    Abstract: A flowmeter which is usually attached to a garden hose or a home shower installation is provided which includes a pipe section in which is mounted a ducted turbine type rotor whose speed of rotation is sensed by an associated coil. The rotor is magnetically polarized. Laminar flow through the rotor which has several blades is provided by a relatively thin flow control plate upstream which in addition to making the flow laminar provides jets which impinge against the rotor blades. A downstream spindle plate also has apertures which isolate downstream turbulence and which includes a spindle shaft on which the rotor is freely mounted. In practice, the flow of the liquid provides a lift to the rotor which allows it to freely float on the spindle shaft to minimize friction. Thus, the overall design has improved accuracy and is very simple in construction.
