General Oceanics Mechanical Flow Meter, Low Speed Green Paper Permanently installed black wax liningProduct Code: 203002 MPN: 2030R6 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
