General Oceanics Mechanical Flow Meter, High Speed Rulers the concave spherical densiometer isProduct Code: 203001 MPN: 2030R These compact, mechanical flow meters are designed for measuring flow in lakes, rivers, canals, estuaries, sewage outfalls, and offshore applications. They are ideal for determining water speed, volume, or distance. These general purpose flow meters incorporate a precision molded rotor coupled directly to a six digit counter that registers each revolution of the rotor and displays it similar to an odometer (up to
