ABSTRACT:
A current meter for measuring velocity in a moving fluid is disclosed which omprises a one-piece plastic bucket wheel retained by a yoke or other suspension device and a signal generating device comprised of fiber optic cables which make and break an infrared light path in order to generate a signal. The fiber optic cables are connected to a vertical shaft which rotates when the pressure of a moving fluid is applied to the bucket wheel, and the signal generated thereby is proportional to the velocity of the fluid. The current meter of the present invention is adapted to be used with a variety of support equipment, such as a wading rod, an ice rod, or a sounding cable with a hanger strap, and thus can be used to measure flow velocity in deep, shallow, slow, or swift streams, as well as in ice-covered rivers.
