ABSTRACT:
A water flow measuring and dispersing device for measuring flow characteristics of a water stream from fire fighting equipment such as a hydrant or pump truck in which the device includes a funnel-shaped housing, a flow measuring meter and a dispersion element. The flow measuring meter is positioned in a neck portion of the housing which is of uniform diameter, and the housing tapers outwardly to a discharge portion having a diameter greater than the neck portion. The dispersion element consists of a crossbar and disc positioned normal to the water flow path in the discharge portion. Dispersion of the stream is enhanced by the infusion of air into the stream caused by the flow of water around the disc.
